Hmm try the Ford section, should be under the pickup-section.

2001 isuzu trooper by caciano

i have 2001 trooper 4w limited edition.Today i was driving my truck and it look like my transmission failed because while driving i started noticing that when i pressed the gas it would make a noice like if the transmission dragged a little,and it would do it only when you came to a complete stop and would try to get speed again so at that time i tried to check the oil level but couldnt fing a stick gage.i also notice a light saying check transmission came up and turn off and did not come back on it just gave me a warning. I look at the bottom of the truk i found some transmission oil leakage very minor,it covered the pan but not leaking in excess or anything do you think is a transmission failure or maybe it could be a broken seal or not enough fluid in the pan ..no problems with reverse gear or any other gears just at the time of punching speed.

You probably lost enough fluid to overheat it. I'd get it drained and filled and go from there.

bad alternator by geagleburger

My 95 Trooper (3.2L DOHC) was freaking out on me. Ocassionally the check trans lights would start flashing along with the air bag light. The tranny would barely start moving and the alt. gauge was pegged at 16 volts. It would dissappear when slowed down (engine RPM's were down) then start running perfect.
     I changed the alternator and it cured everything. Too much voltage was being produced. I had a power steering leak which covered the alternator in muck & goo and probably led to it's demise.

1989 2-dr Trooper with Alternator trouble by bushwacker1

Wow, a site for Troopers! Fantastic.
FIRST HINT OF TROUBLE:
drove home one night and my lights started to go bright and dim as I drove and reved the engine but the next night and there after they ran steady...until it rained, and all my dash lights come on, then the engine stalled and I blew out the Fuel Pump relay.
Charged, dried drove and next rain, all the dash lights came on and it just eventually died
REMEDIES
To check for a short, I have disconected the NEG and attached a test light which did not light so I assume there is no short. I hosed the car from hood, tested again, still no sign of short.
Attached the NEG and a voltmete: Battery still at 12.67
Started the engine. Still 12.67 Reved the engine, no change
Turned on lights, 12.14
Turned of engine, back to roughly 12.6~
Also, when I reved the engineI noticed a "clanking sound' coming from the ALTERNATOR area but couldn't be possitive.
 
QUESTION:
Does it sound like a bad alternator to you?
 
Thanks for your help

Yes, I would say that your alternator is bad. Once you have changed the alternator, hopefully the clanking will be gone. HOWEVER..........if not, then I would check all the belts to make sure no chunks are missing or flipped. If it is a true clanking sound, you may be able to isolate it by carefully using a long screwdriver by placing the tip on various engine parts and placing your ear on the handle .....the sound will be maginified and you can work your way to where it is loudest. I am thinking you have a 4 cylinder, so if you don't know the history, you could have a bad timing belt, or tensioner bearing, or other part that is bad. I think the timing belt is only good for about 60000 miles on your trooper. The clanking sound is usually a symptom when the hydraulic tensioner is bad. I am more familiear with the V6 though.
Let us know what you find and keep us posted! Good luck and WELCOME to the forum! Lot of nice people here that like to help.

geagleburger, I hope you can help me out. I seem to be having a similar problem. My 94 Trooper died one day, took it to NAPA, they said it was probably the alternator. I noticed some goop all over what I believe to be the power steering pressure hose.
 
Did you figure out that all the goop from the leak caused the demise of your alternator? Did you replace the alt and p/s hose? Any info or advice you have would be greatly appriciated!
