GMC Canyon Transmission Recalls

2011 GMC Canyon Recall 11V337000
Summary – According to the recall, the GMC Canyon transmission shift lever may become detached from the transmission shift cable adjuster. If this happens, the transmission shifter won’t work properly, and the gear indicator won’t be able to display the gear that’s actually selected.
Consequence – Should the shifter become detached while the truck is being driven, the driver won’t be able to select Park, even though the shifter is in the correct position. This can lead to an unintended rollaway, resulting in serious property damage and/or injury.
Remedy – This recall began on July 1, 2011, and GMC dealers were instructed to inspect and replace any affected transmission shift cable adjusters, free of charge. Owners can contact GMC at 1-800-462-8782 Or they can call the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236

GMC Canyon Technical Service Bulletins (TSB)

TSB PIP4051C – Harsh Shifting
Problem – Unusually harsh gear changes, combined with a P0717 DTC for an input shaft speed sensor error, are often caused by damage to the ISS sensor wiring.
Solution – If wire damage is found (usually to the white wire), the wiring and sensor will have to be replaced. The pump cover should also be examined for sharp points/edges that could damage the wiring. If any are found, they should be smoothed with a file.

TSB 08-07-30-027 – No movements when transmission is shifted into Drive or third – 4L60E Transmission – 4L65E Transmission – 4L70E Transmission
1982-2005 GM Passenger Cars and Light Duty Trucks: 2006-2007 Buick Rainier – 2006 Cadillac Escalade, Escalade ESV & Escalade EXT – 2006 Chevrolet SSR – 2006-2008 Chevrolet Avalanche – 2006-2008 Chevrolet Colorado – 2006-2008 Chevrolet Express – 2006-2008 Chevrolet Silverado Classic – 2006-2008 Chevrolet Silverado – 2006-2008 Chevrolet Suburban – 2006-2008 Chevrolet Tahoe – 2006-2008 Chevrolet TrailBlazer – 2006 GMC Yukon Denali – 2006 GMC Yukon Denali XL – 2006-2008 GMC Canyon – 2006-2008 GMC Envoy – 2006-2008 GMC Savana – 2006-2008 GMC Sierra Classic – 2006-2008 GMC Sierra – 2006-2008 GMC Yukon – 2006-2008 GMC Yukon XL – 2006 Pontiac GTO – 2006-2007 HUMMER H2 – 2006-2008 HUMMER H3 – 2006-2008 Saab 9-7X – with the 4L60, 4L60E, 4L65E or 4L70E Automatic Transmission (RPOs MD8, M30, M32, M33 or M70)
Problem – It is possible to experience no movement when the transmission is shifted into Drive or the 3rd gear position. It is possible to experience normal operation when the transmission shifted into second, first or reverse.
Solution – Replace the forward sprag assembly

TSB 00-07-30-022D – No reverse, second or fourth gears – 4L60E Transmission & 4L65E Transmission
1993 – 2005 GM passenger cars and light duty trucks
Problem – Drivers may experience the loss of reverse, second and fourth gears. First and third gears will seem to function normally
Solution – The reaction sun gear may fail inside of the sun shell. It will need to be replaced with a stronger heat-treated 4L60E / 4L65 sun gear.

TSB 06-07-30-007A – Harsh 1-2 shift with P0894 DTC – 4L60E Transmission | 4L65 Transmission | 4L70E Transmission
2006 Cadillac Escalade Models – 2006 Chevrolet Light Duty Trucks – 2006 Chevrolet Express Vans – 2006 GMC Light Duty Trucks – 2006 GMC Savana Vans – 2006 Pontiac GTO – 2006 HUMMER H2, H3 – 2006 Saab 9-7X – with 4L60-E / 4L65-E / 4L70-E (RPOs M30, M32, M70) Automatic Transmission
Problem – Drivers may experience an unusually harsh 1-2 shift with a P0894 DTC
Solution – Replace the TCC enable solenoid and/or wiring harness

TSB 08-07-30-008B – Diagnostic information for P0894 and P1870 DTC – 4L60E Transmission | 4L65 Transmission | 4L70E Transmission
2003-2007 GM Passenger Cars and Light Duty Trucks – 2003-2007 HUMMER H2 – 2006-2007 HUMMER H3 – 2005-2007 Saab 9-7X – with 4L60-E, 4L65-E or 4L70-E Automatic Transmission (RPOs M30, M32 or M70)
Problem – This relates to drivers who experience unusually harsh 1-2 shifts, along with a P0804 and/or a P1870 DTC.
Solution – It is possible that a leaking TCC solenoid, a torque converter clutch valve or damaged turbine shaft O-ring seal could cause these two diagnostic trouble codes. However, it could also be caused by a failed torque converter.

PIP5071 – Squawking noise on the 2-3 shift
Problem – An unusual squawking or groaning noise may be heard on the upshift from 2nd to 3rd gear.
Solution – The 3-4 friction and steel plates, clutch plate, apply plate, and selective backing plates will have to be replaced.

PIP5437B – Harsh shifts – 8L45 Transmission | 8L90 Transmission
2016 – 2017 Cadillac ATS – 2016 – 2017 Cadillac CT5 – 2016 – 2017 Cadillac CT6 – 2015 – 2017 Cadillac Escalade – 2016 – 2017 Chevrolet Camaro – 2017 Chevrolet Colorado – 2015 – 2017 Chevrolet Corvette – 2017 Chevrolet Express – 2015 – 2017 Chevrolet Silverado – 2017 GMC Canyon – 2017 GMC Savana – 2015 – 2017 GMC Sierra – 2015 – 2017 GMC Yukon Denali
Problem – One of the more common 8L transmission problems is excessively hard or abrupt gear changes.
Solution – The TCM may need to be recalibrated with the latest control software. It could also be caused by one or more of the clutch fill times not being learned by the TCM. In which case, the Service Fast Learn (SFL) procedure will have to be performed. Should the problems persist, the valve body will need to be replaced.

Common GMC Canyon Transmission Problems 

Intermittent harsh shifting – GMC Canyon 4L60E
Problem – A common GMC Canyon transmission problem is an intermittent hard 1-2 shift, often accompanied by engine bogging. This condition can be caused by the torque convertor clutch applying during the shift.
Solution – To remedy the problem, the wiring harness needs to be inspected from the transmission case connector to the rear of the engine on the driver side. It’s possible that the wires for the TCC solenoid and pressure control solenoid have become frayed on a body seam. If this is the case, the wiring will need to be repaired, and the harness repositioned.

Can I drive with a transmission problem?

If your GMC Canyon can still make it up and down the road, you might say “It’s fine, I’ll just drive it until I can get it fixed”. But that is not always a good idea, depending on the symptoms. You see, there are a lot of (very expensive) moving parts inside of a transmission, and if something isn’t right, continuing to drive with a transmission problem could damage something else.

How often does a GMC Canyon transmission need to be replaced?

The overall lifespan of a GMC Canyon transmission largely depends on how well it was maintained. Factory design flaws also factor into this equation, along with how/how hard you drive. But on average, we’ve seen the GMC Canyon transmission last for between 130,000-180,000 miles. A high quality replacement transmission however, can last considerably longer if all of the factory design flaws have been addressed and the vehicle has been maintained.

How are GMC Canyon transmission issues diagnosed?

It is fairly easy to guesstimate what the root cause of your GMC Canyon transmission problems might be, but you won’t truly know unless you have the right tools and experience. A good mechanic or transmission repair center will be able to connect your truck to a computer and find out which diagnostic trouble codes (DTC’s) have been stored. Once they know what to look for, they can perform a visual inspection to verify the problem.

How is a GMC Canyon transmission replaced?

In order to replace your GMC Canyon transmission, the truck has to be lifted from the ground in order to gain access to all of the parts that will need to be unbolted. Then the transmission can be lowered to the ground (typically with a transmission jack), so the new transmission can be installed. Once it is in place, for the 6L80, the vehicle PCM will have to be reprogrammed / reflashed to accept the new transmission using the latest GM subscription.

How to Solve GMC Canyon Transmission Problems

Solution A: Buy a Used GMC Canyon Transmission

The quickest way to fix your transmission problems is to simply buy a used transmission or used transmission. These can be found at most junk yards, and they often come with a 30-90 day warranty. However, there’s no way to determine the actual condition of the internal components, so you could be spending a bunch of money to have the exact same problems. Plus, that warranty only covers the transmission if it’s defective, not the labor costs that you’ll have to pay.

Solution B: Buy a Rebuilt GMC Canyon Transmission

Another option would be a rebuilt transmission or rebuilt transmission. A local repair shop will remove your transmission, then install a bunch of new parts during the rebuild. The problem here is, the skills and experience of each transmission rebuilder will vary widely from shop to shop, so you could have problems from something that wasn’t adjusted properly. And the 1-2 year warranty might only cover you at certain transmission repair shops, in a specific geographical area.

Solution C: Buy a Remanufactured GMC Canyon Transmission

Many owners depend on their vehicle to commute and get things done. Their gasoline engines are designed to go 100’s of thousands of miles, so it makes sense to invest in a remanufactured transmission.

05 GMC canyon 3.5 auto 4wd. Revs out of 1st and won’t shift unless I drift the rpms way down and float into 2nd. I’ve replaced the harness, solenoids, and everything connected to a wire inside the tranny pan along with the filter, gasket and fluid. No codes referring to the transmission. P0017 & P0335 CPS replaced and cleared but P0449 remains to be fixed. DIY repairs. Can’t figure out what to do with no codes coming back.

It is a 4wheel drive and the bottoms you push to change from 2 to 4 wheel drive you can hear it moving underneath but the clutch don’t hold you can start the truck and with the clutch pedal out you can put it in any gear with no grinding or movement of the truck it’s like something is keeping the clutch disengaged sometime the lock sucuerity light is on and sometimes it goes oit

Trouble shifting in the morning seven sections before I can pull out of my garage nationals going up hill stays in gear is in coming down not sure if it shifts into seventh or eighth gear

5 years ago

I Have a 2006 GMC Canyon that cannot be shifted into gear at the steering wheel. A local shop said I needed a new tranny and wanted almost 3k.$ Does it sound like the transmission, or how do I diagnose the problem further before spending money on a tranny I don’t need?

Would love your thoughts, please comment.x
