What are the DTC codes related to Isuzu Trooper 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 Trooper 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 Trooper transmission need to be replaced?
The overall lifespan of a Isuzu Trooper 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 Trooper 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 Trooper transmission issues diagnosed?
It is fairly easy to guesstimate what the root cause of your Isuzu Trooper 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 Trooper transmission replaced?
In order to replace your Isuzu Trooper 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 Trooper Transmission Problems
Solution A: Buy a Used Isuzu Trooper 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 Trooper 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 Trooper 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.

I have a 2001 Isuzu Trooper with less than 150,000 miles. Someone borrowed it and as they were going up a hill it strained then lost all gears except reverse. You can hear it shift but will not drive. I was told it may just be a shift solenoid problem. Do you think that could be my problem,?
01 trooper, replaced trans 5yrs ago with a jasper refurbished one 43ooo mi on it .slips only when hot 20 or 30 min of driving ,changed fluid twice , now again still slips had a3 yr 100000 mile warranty but jasper accepts no liability. What’s wrong?
My 4l30e will go into gear and it acts like it wants to go but won’t, then sometimes it will go and sometimes it won’t go in all gears, I decided to park it and maybe replace the transmission could you possibly tell me what is wrong with it. I also can smell like a burning smell afterwards sometimes
Slips in 1st gear when hot
Trans does not want to gain speed feels like I’m pulling a tank everywhere I go only while on throttle coasting gains speed but under any throttle it just barely gets up to speed and on a hill under throttle It almost goes to a crawl it’s a 96 trooper 3.2 sohc 4L30E 4×4
I suspect the touque converter but I’m going to try a filter and fluid change and a lucus additive
I have 258 ,000 miles running strong love this SUV
Also is there a newer model trans that will bolt up .. any help is appreciated greatly ..
Travis, you probably need a band adjustment or replacement. My Rodeo has that issue and has less than 50k miles. I changed the filter and adjusted the bands, but slightly over torqued it so problem returned about 3 or 4 months later.
No codes , periodically willit starts out in third gear. Shut off engine restert the transmission shifts correctly again
Check transmission oil temp transmission Check engine warning lights are coming on each time i start my trooper but can delete the codes after its running and they seem to stay off except the check
engine light will reappear moments later.. ran a code check and the code P1860 is what the code scanner is telling me the problem is

Goes into gear but quickly throws overheating error and then seems to slip and not have any power.
GOES INTO 1ST AND REVERSE, BUT WILL NOT CHANGE GEARS. REPLACED SOLENOIDS, FLUID AND STILL THE SAME.
same issue, did you fix it? and how?
