Question about 2001 Isuzu Trooper

2002 Isuzu Trooper Transimission

Our Trooper had the transmission replaced at 33K miles. It now has 80K and has begun to shift erratically when under strain, like going up a steep hill. It feels like to me that the lock-up converter if it has one is disengaging and reengaging. It happens quickly and rarely long enough to see the rpm's jump up and then right back down? Any help would be appreciated. Also, this problem just suddenly appear, wasn't happening one day started the next?

    I have the same problem. In fact, my 2001 Trooper is back at the dealership for this very problem. The first time I took it in this week they claimed I must have put the 4W shifter in neutral. This was of course not the problem. After breaking down twice in 24 hours it is back at the dealership today. I have 90K on my Trooper (our 4th by the way) and have had more trouble with this car than the 3 previous ones. When my Trooper shifts erratically it is usually on an excelleration and the transmission disengages completely leaving me without power. When the car "cools down" I can start it and it is anyone's guess as to when it will disengage/reengage again.

Take back to dealer and ask them to put in trans shift additive. Worked for my 2001 Trooper.

I just bought a 2002 trooper, 142k miles. Where is the transmission / power steering dip stick ?

The transmission doesn't have a dip stick you will have to take some where and have them check it, unless you feel comfortable doing it your self. The power steering on the other hand. If you pop the hood look around you should see a black cap that says powersteering fluid, when you take the cap off it should have a dip stick attached to the lid if not there will be a fluid level mark on the side of the tank, which you took the lid off of.

1995 Isuzu Trooper v6 180k miles. Veh has been

Ya sounds like the electric shift solenoid. Problem with electrical. Will not give you a warning. Will go bad in a heartbeat. You can try unhooking plug that gos into the trans and spray electrical cleaner on it. plug back in. Wiggle some wires and maybe find one loose or broken wire or connection and hope for the best. But its probably the tranny with that many miles. Go to Advance Auto Parts they usually scan your car for free for codes. Good luck

1995 isuzu trooper limited edition transmission jumps into overdrive as soon as yu take off. is there an electronic shifting device under pan? can i do a resistance test if so?

Yes there is but that does not control the overdrive engagement. no a resistance test can't be done on that unit.

You problem is more involved and will require a transmission expert to look at it and diagnose it properly.

I have an automatic Isuzu trooper 1996, it shifts wrong

You need to get the transmission serviced. Either the Filter is clogged or something has worn out and needs to be repaired.

If the fluid is up -
it could be a vacume loss or the shifting module..
The shifting module is what tells it to shift - and it is controled by vacume pressure..

Not much power from a V-6 engine

1. Replace Fuel pump and
2. Replace Transmission.

But you can also do a scan.
