What are the DTC codes related to Isuzu Rodeo transmission problems?

P0766 – Failed Shift Solenoid D – This DTC can be stored when there is a problem with a shift solenoid or the valve body.
P2703 – Failed Friction Element D – This trouble code can be triggered by a failed friction element like a clutch disc.
P0720 – Failed Input Speed Sensor or Output Speed Sensor – This trouble code is caused by a bad speed sensor on the transmission.
P0730 – Incorrect Gear Ratio – This issue could be caused by a number of problems, including a fault in the transmission control module, dirty transmission fluid, or a bad transmission solenoid.
P0657 – Voltage Problem in the ‘A’ Circuit – This transmission problem is often caused by a short, or bad ground on the PCM or PCM wiring harness.
P0700 – Malfunction in the transmission control system – This DTC is often triggered when there is a problem with the TCM, a wiring harness, a solenoid, or the valve body.
P0715 – Input/Turbine Speed Sensor Malfunction – This code typically gets stored when the input sensor cannot read the engine RPM, which can prevent the transmission from appropriately shifting gears.
P0717 – Input/Turbine Speed Sensor No Signal – This trouble code is generated when the PCM does not get a signal from the input speed sensor, which will prevent the computer from being able to determine when the transmission needs to shift.
P0791 – Intermediate Shaft Speed Sensor ‘A’ Circuit – This error can occur when there is a problem with the intermediate shaft speed sensor, most likely due to a bad sensor, wiring problem, or a failed shift solenoid.
P0793 – Intermediate Shaft Speed Sensor Circuit No Signal – The computer will generate this DTC when it cannot communicate with the intermediate shaft speed sensor.

Can I drive with a transmission problem?

If your Isuzu Rodeo 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 Isuzu Rodeo transmission need to be replaced?

The overall lifespan of a Isuzu Rodeo 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 Isuzu Rodeo 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 Isuzu Rodeo transmission issues diagnosed?

It is fairly easy to guesstimate what the root cause of your Isuzu Rodeo 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 Isuzu Rodeo transmission replaced?

In order to replace your Isuzu Rodeo 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.

How to Solve Isuzu Rodeo Transmission Problems

Solution A: Buy a Used Isuzu Rodeo 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 Isuzu Rodeo 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 Isuzu Rodeo 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.

Often slips going into OD sometimes shifts into OD hard and trans light blinks , but resets after turning off eng and restarting, no codes are stored. Sometimes after letting off the throttle it will just jump into neutral and you need to pull it into 3rd to drive .

It’s a 4l30e trans

I bought it with oversized tires (31 in. diameter) and had my perfectly working trans from my other rodeo put in it. It’s taken me a month to get my original wheels / tires back on it. The over sized tires made my speedo read 5mph slower than I was going, and made it much harder to get into overdrive (52 mph the tach drops from 2200 rpm to 1800 rpm). This killed my gas mileage and power. Now the trans seems to be slipping turning right and sometimes going straight (mostly when it’s not warmed up) . I have been babying it , and notice sometimes it seems to work perfectly well. I had a similar problem with another one that would slip when going around corners and they replaced the electronic magnet looking units inside the trans. I will be using this to tow a 5×8 trailer (600lbs.) that has 3,000 lb springs on it. I don’t plan on towing anything tat heavy, but maybe 1,000 lbs on it.

I have a 2000 isuzu rodeo 3.2 2wd 4l30e. And when it rains it will jump out of gear. If I pull over and turn ignition off for a few seconds then start back up it shifts fine. Also its throwing a b solinoid code. But also when it rains it will shift no problem.

Won’t shift out of 2nd

Hi I have a 2000 Isuzu rodeo 3.2 with automatic four-wheel-drive vehicle 148,000miles and no OBD2 codes no quotes on price
it starts right up but when you go to put it in gear if feels like there’s just an extreme extra load and it shuts right off almost as if the parking brake was on but it’s not
As soon as you put it in gear any of the forward speeds the RPMs climb up to about 2000rpm and then drops then car shuts off like it’s under a load like it’s trying to move and can’t I haven’t checked the fluid yet that could be an instant indicator of maybe what the problem might be maybe the pump on the transmission? Torque Converter? Any ideas thank you
Since there’s no dipstick I’m gonna have to get under there and drain a sample amount or drain it completely look at the fluid and re-pump it back in if it’s OK

I don’t know if you’ve recently had transmission out or done work on it but it sounds like the tcc solenoid located in the front pan could be your problem. If stuck it will cause this type of engine stall. The reason I mentioned recent work is the square 4 wire connector for the tcc and force motor solenoids in the front pan section can easily be plugged in incorrectly. The locator tabs are known to break off which allows them to be installed in the wrong position and also cause this stalling condition.
