The GM 6T70 / 6T75E transmission first saw production in 2007 GM models. The transmission fits both front and all-wheel-drive vehicles.

GM and Ford Company cooperated in 2002 to create a new automatic transmission/transaxle designed for transverse engines SUV’s and cars. Each manufactured the transmission separately and named them different models, IE GM: 6T70, 6T75  Ford: 6F50, 6F55, 6F35.

Prior to 2009, this transmission had issues caused by a weak 3,5,R wave plate, which made this transmission prone to failure. Updated wave plates were released for many clutches in the 6T70. The old design wave plates were not stress relieved and could break with use.

6T70 Transmission & 6T75 Transmission Recalls

Recall 08V200000 – Failed parking prawl
2008 Saturn Vue 6T70 Transmission

Summary –
Back in 2008, General Motors recalled some 26 2008 Saturn VUE models equipped with the 6T70E 6-speed automatic transmission. Seems that the transmission case side bore that holds the park prawl pivot pin may fail to secure the transmission in the Park position, due to a flaw in the casting.

Consequence –
If this happens on a “non-level” surface, the vehicle could unexpectedly roll away, causing serious injury and property damage.

Remedy –
Dealers were instructed to replace the transmission. Owners should direct questions to the National Highway Traffic Safety Administration at 1-888-327-4236

Recall 09V073000 / 09041 Transmission shift cable clip failure
2009 Buick Enclave, 2009 Chevrolet Cobalt, 2009 Chevrolet HHR, 2009 Chevrolet Malibu, 2009 Chevrolet Traverse, 2009 GMC Acadia, 2009 Pontiac G5, 2009 Pontiac G6, 2009 Saturn Aura, 2009 Saturn Outlook

Summary –
On 276,729 2009 GM vehicles, the transmission shift cable adjustment clip may come loose, causing the gear indicator to display the wrong gear.

Consequence –
If this problem occurs, the driver could remove the ignition key and exit the vehicle thinking the transmission is in Park, even though it isn’t. This can lead to a rollaway, which can cause injury and/or property damage. A lesser consequence would be the inability to start the vehicle because the transmission is not in Park.

Remedy –
This recall began on March 24, 2009, and Chevrolet dealers were instructed to inspect and if necessary, replace the shift adjustment cable clip. Concerned owners can contact the National Highway Traffic Safety Administration at 1-888-327-4236

Recall 13V097000 – Reduced engine braking
2013 Buick LaCrosse – 2013 Cadillac SRX

Summary –
On certain models of the 2013 Buick LaCrosse and 2013 Cadillac SRX, the transmission may inadvertently shift into ‘Sport Mode’, reducing any engine braking effect.

Consequence –
As a result of losing engine braking, the vehicle may not slow as expected, increasing the risk of a crash.

Remedy –
To fix this problem, GM released a software update for the transmission control module/TCM, and will install it free of charge. Owners can contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236

6T70 Transmission & 6T75 Transmission Technical Service Bulletins | TSBs

TSB 07-07-30-019 – Check engine light on with poor vehicle performance – 6T70 Transmission | 6T75 Transmission
2008 Buick Enclave – 2007 GMC Acadia – 2007 Pontiac G6 – 2007 Saturn Aura – 2007 Saturn Outlook
Problem – Drivers may experience poor engine/transmission performance, along with the following transmission diagnostic trouble codes: P0716, P0717, P0722, P0723, P0751, P0756, P0776, P0796, P2714, P2723
Solution – These transmission problems may be caused by a failed speed sensor

PIP4627A – 35R clutch wave plate broken – 6T70 Transmission | 6T75 Transmission
2007 – 2009 Saturn Aura – 2007 – 2009 Saturn Outlook – 2008 – 2009 Saturn Vue – 2007 – 2009 GMC Acadia – 2007 – 2009 Pontiac G5 – 2008 – 2009 Pontiac Torrent – 2008 – 2009 Buick Enclave – 2008 – 2009 Chevrolet Equinox – 2008 – 2009 Chevrolet Malibu – 2009 Chevrolet Traverse
Problem – On vehicles equipped with the 3.6L V6 and 6-speed automatic transmission, drivers may experience no reverse, slipping, and/or harsh shifting between 3rd-5th gears. They may also have diagnostic trouble codes P0776 and P0842. This condition is typically caused by a broken 35R clutch wave plate.
Solution – During the repair/rebuild process, the wave plate must be installed properly (with the rounded edge of the internal splines facing the 35R piston), in order to prevent premature failure.

TSB 13120A – Torque converter clutch sticking – 6T70 Transmission | 6T75 Transmission
2013 Buick Enclave – 2013 Cadillac SRX – 2013 Cadillac XTS – 2013 Chevrolet Malibu – 2013 Chevrolet Traverse – 2013 GMC Acadia – 2013 GMC Terrain
Problem – The torque converter clutch solenoid can stick due to debris in the transmission. When the vehicle is at the end of a coast-down, as the vehicle is coming to a stop, a stuck solenoid will fail to release the torque converter clutch. This keeps the engine directly connected to the driven wheels. As the vehicle stops, the engine speed will be pulled down below normal idle speed and the engine may stall. The vehicle can be immediately restarted and driven.
Solution – The valve control solenoid should be replaced, and the transmission control module will have to be reprogrammed in order to correct the problem.

Common Problems with the 6T70 / 6T75E

Input/Output Speed Sensor Issues – 6T70E Transmission
Problem – When repairing a failed input speed sensor or output speed sensor, steering system damage could occur.
Solution – To avoid damage to the clock springs, the splined steering knuckle must be prevented from falling out of the steering rack when dropping the subframe to access the valve body.

One of the most common 6T75E transmission problems is overheating. This happens when the moving parts inside the transmission are creating more friction heat than the ATF can remove. The most common cause of this condition is towing heavy loads, driving in stop/go traffic, or on mountain roads where the transmission has to shift a lot.

Overfilling the transmission with too much ATF can also cause 6T75E transmission overheating, which can lead to ruptured seals, and damaged torque converters, valve bodies, bands, and clutches. An auxiliary transmission cooler can do a lot to help keep the temperature down.

Another common issue with the GM 6T75E transmission is broken wave plates. These metal disks help to lock gears together during a shift. If they break, the metal fragments will get hurled through the gearbox, causing catastrophic damage to other internal components. There isn’t a lot that you can do to prevent this problem, but a remanufactured GMC Acadia transmission can ensure that it won’t happen again.

You can also cause the transmission to overheat with improper maintenance or abuse. The main things you need to watch out for are overtowing and revving too much. These cause the transmission to rev too high and strip gears or use too much transmission fluid. The best thing to do, if you think the transmission is overheating, is to pull to the side of the road and let the vehicle cool down.

When a gear change is required, the computer tells a little spring-loaded plunger in the valve body to move and direct pressurized ATF into the appropriate channel. There’s one of these solenoids for each gear, and it’s activated by sending current through the coil of wire that’s wrapped around it. The problem is, that coil of wire can short out, or excessive vibration can shake it loose, causing the solenoid to fail.

Updates to Remanufactured 6T70 / 6T75E  Transmissions

  • Torque converter support bearing fully inspected to prevent sleeve failure.
  • Completely remanufactured pump, including polishing of pump rotor mating surfaces, provides consistent internal pressures and helps eliminate pressure-related issues.
  • Remanufactured and tested valve body to improve shifting, lubrication, and performance.
  • Transmission Control Module (TCM) tested for proper function of pressure control solenoids, shift solenoids, and pressure switches.
  • Clutch clearances set to custom-spec standards for improved shift feel and timing.
  • Updated 3,5,R wave plate, which made this transmission prone to failure pre 2009.
  • Fully remanufactured torque converter is tested for leaks, lock-up, concentricity, and balance. Upgrades exceed OE requirements and eliminate the possibilities of front seal leaks, premature bushing wear, and vibration.
  • All new, bushings installed in key locations to improve internal fluid flow control and fluid pressures.
  • Complete system correction and recalibration kit installed to address several OE flaws. Modifications include updates to servos, the PR system, and valve body accumulators.

How to Buy a Remanufactured 6T70 / 6T75E Transmission

1) Buying Locally

When you go to your local repair shop, they’ll order a remanufactured 6T70 / 6T75E transmission, then mark up the price. So at the end of the day, you’ll be paying 15% to 30% more than the actual cost of the unit.

2) Buying Online

Buying a reman transmission through a company like Street Smart Transmission will save you a considerable amount of money because you pay the wholesale price (avoiding a repair shop’s 15% to 30% markup), they’ll ship the unit to the shop of your choice free of charge, and returning your old transmission is free as well. Then all you have to pay for is the labor to install the unit (usually $400 to $800), and you’re on your way.

How Does it Work?

To order a remanufactured transmission from a company like Street Smart Transmission, all you need to do is provide your vehicle’s VIN number, the mileage, and the address of the repair shop that you want it shipped to.

Financing

Replacing a transmission can be expensive, so Street Smart Transmission offers financing through PayPal Credit. Depending on your credit, you’ll be able to order a new transmission, get back on the road, then pay for it over time. You may have to pay labor charges for the installation up front, but you won’t have to shell out for the transmission all at once.

Shipping Charge/Location

When it comes to shipping, a transmission is quite heavy. So you’re going to pay quite a bit of money, unless the reman transmission company offers free shipping. Street Smart offers free shipping to a business address, which is usually the repair shop that you’ve chosen to install the unit.

What is a Core Charge (Core Deposit)?

Every remanufactured transmission originally came from somebody else’s car. Therefore, they need your broken transmission in order to refurbish it for another customer.

Your old/damaged transmission is called a “core”, and many companies will collect a core charge (usually $500 to $1500), which will be refunded once they receive your old transmission. (Street Smart does not charge an up-front core charge.) Make sure to ask any company for their core return policy, so you’ll know what to expect.

Easy Core Return

Our Recommendation

We recommend Street Smart Transmission. We have found Street Smart to be of the highest quality. Their transmissions carry a 3 year / unlimited miles warranty that covers both parts and labor. Their warranty is nationwide and attached to the VIN so it is transferable with ownership if you decide to sell the vehicle. It also covers both parts and labor for the installation of the replacement transmission.
