#145 of 167 2000 trooper trans just rebuilt-new probs
May 30, 2012 (9:17 am)
Hi fellas, and thanks for all your help a few years back after my first rebuild nightmare in 2008.
A "hack" tranny shop "rebuilt" my trans, it was never right, they even gave it to me, I found out much later, with 5 stripped pan bolts, one of which they had literally stuck a PAPERCLIP in so that the bolt would tighten at all.
I've had a horrible 3 years of little or no income, so I've been driving it it limp mode using 1st and 2nd manually, and to my amazement, it's kept letting me.
Recently, I was able to get my finances in better shape, and at first decided to unload the trooper as many mechanics had recommended I do, and try to find a reliable car for around $3,500. After months of car shopping, I wound up paying homage to my reliable engine and too much attention to my deep adoration of my huge double-size moonroof, and decided to fix this transmission again instead.
One of my main problems has been deciding just what to do. I came close twice to trading in the trooper on small car lots, but I was too unsure about the replacement vehicle. I did a lot of research on all of the cars I looked at, too. I ALSO CAN'T GET A HANDLE ON WHETHER THE
TROOPER IS SOMETHING I SHOULD KEEP, LET ALONE SPEND BIG BUCKS ON.
My current dilemma:
I just spent $1,900 getting my tranny rebuilt again, by a shop who was helpful during the last siege. When he was done, he said "it has a vibration that is coming from the front axle" I told him there was no vibration before, but I was so sure he had truly fixed the transmission, and as I drove away I felt nothing noticeable.
By the time I had driven 8 miles or so, there was a horrible grinding, catching, and shuddering as I came to a stop, and as I began to accelerate. In subsequent days this has continued consistently, as soon as it's warmed up. I called the rebuild place, they insisted it was the axle, but said I could bring it back Tuesday after Memorial day. Over the weekend I decided it would be prudent to get some more local opinions for ammunition before I went two cities over to the rebuild shop.
Two general mechanics whom I believe are less likely to be dishonest than most had multiple mech's drive the car and believe it is the tranny, not the axle. I went to an AAmco in town (to whom I told the whole story) who supposedly did a lot of testing and to my surprise, showed me that it was the axle (both boots are blown) and he wiggled the front tires and said that the wheel bearings were bad. He then said that these two conditions would produce the symptoms I was having. HAS ANYONE EVER HEARD OF THIS?
I went back to my trusted mech, who put it back on the rack, drove it again, specifically paying attention to the axle, bearings, and the rest of the drive train, and cannot produce while on the rack, any friction or wobble that would create the problem. I went to another general mech and the-most-respected tranny people in town (expensive #$%) this morning, and they also believe it is an internal transmission problem.
Unfortunately, I called the rebuild shop after seeing AAmco and told them it looks like he was right. I no longer believe that.
The rebuild shop had said my tranny was extremely burned, and that he had to go into the valve case 3 times (with test drives in between) to get it clean. Can my symptoms be related to remaining grunge, or does it sound like something else?
Most of all, is there any chance that the axle and wheel bearings CAN produce these symptoms? Should I have my mechanic fix them for another $1,000 against his better judgement? Should I put another $1,000 into this car at all? It has occurred to me that since I told AAmco everything, they knew they were'nt going to make any TRANNY money off me, and came up with something I had reason to buy into that they could do.
PLEASE HELP. In 2008 I went through all the appropriate channels and filed all the appropriate complaints, thru to DACS and the office of the Atty General, and even went to ABC Action News for help. At least the ABC volunteer assigned to my case had the integrity to be appalled by the blatent lack of appropriate response from the officials.
I've read your wonderful forums and know that these Isuzu transmissions can reduce grown men to tears. I'm a girl.

Wow! I'm exhausted just reading your dilemma... The front end noise is, in fact, the wheel bearings. Repacking the wheel bearings is to be done every 50k anyway and is usually $50-80 a wheel. It sounds like you have a 4WD, however 2WD vehicles require the same. It's the SUV nature.
Trooper owner/enthusiasts are an odd and magnificent lot. We like working on them. We love the international heritage Troopers they maintain, and their subtle yet uncanny ability to keep going. Thing is, your previous owners have 4-wheeled that thing rather harshly-that being said, it's really OK.
Your car has value, so you probably should sell it and get a 95 Camry (also indestructible yet more reliable)
Mechanics pull those stunts all the time, to all of us. It's shameful and shi%%y yet everyone pretends it doesn't happen to them. It appears as if you're doing everything correct, so keep up the fight...

#149 of 167 Replace Transmission Pan But Still very small leak
Sep 30, 2012 (9:38 pm)
I looked through all the threads and couldn't find any information on anyone that actually worked on their transmission. Yeah I know how to replace the transmission fluid in a Isuzu trooper. The problem is I don't know what the recommended torque is for tightening the bolts around the transmission pan. I did a start pattern with a new gasket, but it still leaks. I am wondering about just puting some Lucas transmission gasket seal fluid in with the ATF.
Any suggestions would help.

Yeah, i got it. I used a cheap thin rubber gasket at first and the tranny leaked. I got a good rubber one with some cork composite from Fram. I over tightened one of the bolts trying to torque the bolts at the right inch pounds vs. foot pounds. Anyway, long story short just tighten the bolts with a regular wrench and tighten well, but remember those bolts strip really easy, so don't over do it.
Some people were telling me to use a silicone seal on both sides of the gasket and I talked to a transmission guy who said transmission gaskets are always a dry fit. That's what worked for me. The gasket from Fram is a nice composite of cork and rubber. The cork expands making the fit tight under pressure.
#152 of 167 Isuzu Trooper Engine Heavy/Revving and Drastic Fuel Economy Drop
Apr 01, 2013 (7:21 pm)
Hi, I have an isuzu trooper, 2000, 6cyl, 4wheel drive, 73k miles. Had been experiencing stalling and some loss of power. Egr valve, air intake manifold gasket, fuel pump changed. Had oil change and fuel injectors cleaned, idle cleaned, had spark plugs, timing belt, oxygen sensor , brakes checked, check for vacuum/fluid leaks, mechanic said they were ok.
No more stalling, but car does not feel right, starts very heavy and rides like that a while, especially when foot on gas, gas economy has suddenly dropped from 15 to 9 mpg. Engine also feels like revving sometimes.
Any thoughts would be grealy appreciated, love this suv, thank you

You must get a diagnostic code reading before going any further. YOu might find an 02 sensor issue, there are 4. Also, the H20 temp sensor is a very important component with these types of issues. Replacing is simple and inexpensive..$20.
How does one "check" the timing belt? I just replaced mine at 99,720 on my 2002 Trooper and it looked fine (although a little dried out).
Finally, you must consider that these if you are not the original owner it has probably been 4-wheeled in deep water, which mean accelerated dry rotting of the vacuum lines/connectors. The fuel consumption issues on this model is usually associated with the fuel system. Also, check the transfer case, axle, differential and LSD fluid levels. You will be amazed at the capacity levels these units hold.

Thanks for your reply. I am not original owner, but bought it when it was less than yr., so have had since 2001. No check engine lights have come up through this whole ordeal. We had a diagnostic run , only Egr came back as an issue.
They put in a new one, but still stalled, that's when intake manifold gasket was replaced and put in new fuel pump . Stalling stopped.
Issue is really that heavy/revving of engine and sudden fuel consumption drop.
I will have O2 and H20 sensors rechecked.
Would bad timing belt cause any of this.
Since they changed pump, filter, cleaned fuel injectors, ran tests for vacuum/hose leaks, what else should I have check on fuel system.
Also, brought it to a different mechanic today and while he couldn't pinpoint cause of issues I mentioned earlier, he thinks there is an engine issue, when he put car in neutral and stepped on gas, there was a slight ticking noise. Does this sound true.
Thanks a million.
