Hi, It is possible for you to check for trouble codes on your vehicle. If you get a code and need help, post again.
1995 Isuzu Truck Trooper (2 Door) V6-3165cc 3.2L DOHC (6VD1)
Vehicle Level Transmission and Drivetrain Transmission Control Systems Testing and Inspection Testing and Inspection Procedures Displaying and Reading Trouble Codes
Displaying and Reading Trouble Codes
This is a link to a diagram of locating the jumpers.
DTC can be displayed by the Transmission Control Module (TCM) by shorting together terminals 1 and 2 of the TCM Diagnosis Connector (C-92) located left side of left instrument panel (This grounds the TCM pin D16).
After this, the CHECK TRANS Indicator will be OFF for 3.2 second and then will flash each DTC 3 times.
When there are more than 9 flashes this means that the indicator is constantly flashing, OFF for 0.4 seconds, ON for 0.4 seconds. In this case there is no DTC stored in memory. To find the problem without a scan tool and without DTC GOTO WITHOUT DTC CHECK.
When there are less than 9 flashes you will see DTC of 2 digits repeated 3 times each and when all codes have been displayed they are displayed again beginning from the first one.
Do not care about the DTC order : if "21" is before "22" it does not matter.
Write down all codes numbers and GOTO DTC CHECK.
IF CHECK TRANS indicator is not flashing GOTO "CHECK TRANS" CHECK.

I'm brand new here, so forgive me if I err hugely!
I have a '93 Trooper who is my pride and joy. I have had her for 2 years, third owner. When I bought her I did some preventive maint. stuff (brakes, tires, timing belt, clutch,etc)--and she runs great. She's got 111k and my issue now is a fuel smell/leak in the engine compartment. Needless to say, she is parked. Other than the smell and obvious leak, she runs great (best in cold weather)no stalling nothing. We can't find the source of the leak. My questions: Is it about time for an overhaul? Should I consider an overhaul? Would an overhaul replace parts that might be causing the fuel leak? (I'm assuming it is something along the line of worn hoses and the like) Should I instead just concentrate on letting a mechanic find just the leak? I intend to keep this Trooper until the wheels fall off so an overhaul is just a matter of time. Please forgive my total inexperience with vehicles, this is my second car--and I'm quite attached to her.

Hi, the gas smell could be from a variety of sources, but an overhaul might be overkill. The fuel system is pressurized by a pump in the fuel tank, and the pump only turns on for about 2 seconds when you first turn the key on. Then it will turn on when it sees oil pressure from the engine running or from cranking long enough to do same. That means that when your trooper is not running and just sitting, there may not be enough fuel pressure to spot a drip or pool of fuel, and if the engine is running the fuel may vaporize too fast to see due to the heat. The bottom line is the fuel system should be inspected from tank to fuel injector, and care must be taken to insure no injury to you or the vehicle. If you can't spot or isolate the location yourself, then a mechanic would be your best choice. Your trooper does not need an overhaul just to fix a leak. If you search this forum you will find many Troopers with far more miles than yours and no overhaul. The complexity of the fuel system with its' O-rings and connections may just be more than the casual car owner can handle. I hope this info helps you decide what to do. One owners opinion!

I found my 2000 trooper's Check Trans light on. At low speed, when I speed up slowly, I can feel the shake of the car. Anybody now the reason? Please help.
#31 of 383 '99 Trooper with a host of sudden problems
Sep 25, 2006 (11:23 am)
My '99 Trooper has been performing like a charm for all of her 136,000 miles. But on Labor Day, I had driven only about 100 yards out of my driveway when she bucked twice and stopped dead: the electrical system was instantaneously and completely flat. The rapair shop towed the Trooper and installed a new battery, and I went on my way. Then two weekends ago, she started bucking again on the Interstate and then lost almost all power. Towed again. This time the air mass sensor was replaced and away I went. For the past few days, the Trooper has been surging not only when the engine is under load but sometimes at normal speed on a flat roadway. The repair guys see no problem codes on the computer. I don't want to spend a lot of money unnecessarily, but I'd like to continue my long and happy relationship with this fine vehicle. Any ideas?

Sent it to Dealer and told me low speed transmission sensor is bad. Changed it. $550
#33 of 383 '96 Trooper Transmission mystery-need help
Sep 28, 2006 (7:42 pm)
Our '96 Automatic Trooper needed a transmission replacement (lost reverse completely) and since then the replacement transmission has been nothing but problems, it runs fine for a while after the shop "fixes" it, then it acts up. Currently it seems like it's not downshifting back to 1st gear after reaching a certain speed or distance or both. When you come to a stop, then start up again, it feels like the truck is in 3rd gear...the mechanic can't figure it out...anybody??

Hi, is there any chance that you have the winter switch in winter mode.....that option commands the trans to start in 3rd to increase traction when driving in slippery conditions?
I have to wonder though, that if your original trans was OK except for reverse, then the new trans does not sound like it was built properly if you have had problems with it since installation.
You might inquire if the mechanic used a scan tool to check for trouble codes that might be set in the transmission controller. Good luck

I spoke to a man the other day that had the same problem (battery drain) check the positive cable all the way ....his insulator had melted close to the head light causing a short to ground thus draining the battery upon sitting......good luck
