I recently had transmission problem with my 2000 Isuzu trooper. It started with a feeling of slippage in and out of overdrive and ended with jerking.. They had to rebuild the whole thing for 2400.00 Ther eare some places that will do a free transmission check, it may be something simple that doesn't cost as much as mine did, But I would just call around and see if they do free estimates and free checks...
GOOD LUCK!!!

I am the 2nd owner of a 2000 Trooper with 85,000 miles on it. My automatic transmission (4L30E) failed a month ago. I was experiencing neutral drops and severe slipping while driving. I took it to a reputable long established, privately owned ATRA approved transmission shop. I was advised to replace the bad transmission with a re-manufactured JASPER transmission. The shop had my Trooper for 5 days and returned it to me with the installed JASPER transmission. It ran beautifully for about a week then all the sudden the JASPER trans started slipping bad between 2nd - 3rd gear. I returned to the trans shop and the tech took it for a test drive and confirmed that there was a problem with the new trans. I left it there and they did pressure tests on the trans and found it to be defective. After a week I got the Trooper back again with the 2nd new JASPER transmission installed.
The next day as I was driving the trans started making a loud "buzzing" sound in 3rd gear which at first was intermittent but became more frequent over the course of a couple days. I have called the shop again and was told to bring it in for another test drive. I am now concerned that all the transmission test drives which I've been told are hard on an engine because of necessary revving procedures done during those rides combined with the Trooper 3 series engines not have a great reputation is going to lead to other problems. Also, as a younger man I worked as a helper at an auto repair shop and learned that some shop owners are only so honest, occasionally when a vehicle became a liability the vehicle was abused to the point of developing an unrelated problem that would not be worth repairing. From what I understand a JASPER transmission is supposed to be the "Gold Standard" of re-manufactured transmissions, I guess there are exceptions to every rule.

#134 of 383 94 Trooper spark plug wires by bluecatfish88

Does anyone know WHY the company who built the Trooper recessed the spark plugs 10 inches into the engine ????
That's about the most ignorant design I've seen.
Now with that off my chest, the question I have is why do the rubber ends on the spark plug wires keep coming off, & remain stuck around the spark plug, in a manner that you have to "fish" them out with a clothes-hanger ? This is VERY aggrivating, when the plugs are so far into the motor, you can't reach them with your fingers, or any other tools for that matter. Could somebody explain to me why this happens ???

Have you ever had occasion to work with Automotive Engineers? I do daily and it can be an interesting experience to say the least. I have seen some of them grab hot exhaust pipes and welded parts immediately after seeing them being red from heat....and burning their hands in the process.
As to your question, even conventional spark plug boots stick to the plug after time. The trick is to use dielectric silicone grease on the inside of the boot BEFORE putting it on the plug. This insures it will not affect performance and the boot will detach from the plug more easily. the grease is available at auto parts stores. Sometimes a slow, twisting pulling motion will help break the hold of the boot on the plug. I believe the heat and proximity of the boot to the plug cause this bonding to occur. Most owners manuals suggest that the boot be twisted on the plug to free them before attempting to remove the boot from the plug. Hope this helps.

Trick to remove the rubber ends from plugs when stuck.
 
I went through the drill when I replaced mine a couple of years ago. Use compressed air from a source such an a little 12 volt inflater or a real compressor. I used one of those little tapered attachments you might use for inflating an air mattress. Insert in the center hole where the plug is at the bottom of the stuck boot...a little burst of air pressure and the rubber boot pops right off.
 
I pulled and twisted and could not get the last one off...after 2 evenings of that and driving with 5 new and 1 old plug, I finally came up with that method. Don't want to break or tear one of the boots since I have been told you can only buy the complete coil over package that includes the boot.

That will work. I will try putting that grease on those plug ends. But there's still one question that remains unexplained. Who's bright idea was it to recess the plugs in the first place ?? All over types of vehicles that do not have recessed plugs, I've owned over the years, I never had this type of problem. It's easy, simple & anybody can change the wires. Who came up with the recessed spark plug idea, & why ??

I will go out on a limb here and guess that the designer had to place the plug in a location that was dictated more by the valve train design (4 valve/cyl) than by practical concerns. The Valve cover area is huge for the size of the engine. The Hemi Engine had a center mounted plug design too, but no where near the depth of the Isuzu. Sound close?

#139 of 383 2000 Isuzu Trooper transmission failure by rck13str

I purchased my 2000 Isuzu Trooper used from a well-known auto dealership in Knoxville, TN, with 96,000 miles. Less than 2 months later the transmission went-out. (No wonder they wanted to get rid of it so quickly!) At 146k miles, almost 2 years later, and after $2,500 spent for new transmission, vehicle runs fine.

I'm new,I do not know if I am posting in the right area.
 
I have a 1999 Isuzu Trooper. I've had the starter replaced three times in the last year. Any suggestions to what is causing this?

Bill,
 
Have you had any problems with your engine, specifically with the rod bearings?
