I need to pay more attention next time it happens. I don't think the wheels are spinning. The revs are going up, either without movement or with less movement than you would expect given that the revs jump up to 2500-3000 RPM pretty quick.
It's almost like the engine is getting ahead of the transmission or something.
I thought the fluid level check was with the engine running, but I didn't remember anything about the "trans in Drive" requirement. That's not how I checked it last time; maybe that meant my reading was off?

My second concerned is what is Torque on Demand? and how it functioned? Is it something link with ABS or ECU? I'm really confuse on this TOD system...Please Help!!!!!!
I am in a miserable situation. Recently i bought a 1999 isuzu trooper with TOD function which i have no idea on it. Anybody can help me to understand about this TOD.
A deepwell impact socket will not work since the walls are thicker, and the spark plug is not held in place correctly with one. HTH
Can you give some specifics about the Trooper and what you're looking to get out of it...
If you don't have a socket with the rubber insert, one of the magnetic extensions would work to remove the old plug once it is loose, but it would be much easier with the real spark socket for getting the new plugs started. Remember these are aluminum heads....don't want to get them threaded incorrectly.
Get the codes read....the OBD system has the capability to tell you which sensor is causing the CEL. Hope this helps. One guys opinion.
Thanks in advance!!!
I'm not sure if anyone will have the info, but I am thinking about swapping out my engine on my 1990 Isuzu Trooper 5 speed 2.8 liter v6. I want to do so because i have about 190,000 on the engine, and the power has diminished greatly thru the years. My 1990 Trooper is in mint condition, and I don't want to give it up. Not just yet anyways.
I guess I am asking what route to go. Will rebuilding the engine be the way. I would like to maybe throw another engine in, but its difficult to find anything out there with lower miles on it. Is there maybe another engine out there which will work in my 90 Trooper? Another engine with more horsepower?
I have never rebuilt another engine before, but swapping engines/transmissions/ etc... have never been a problem for me.
If there is anyone out there who can help, it would be greatly appreciated....
As for the engine replacement, Would I need to find the same year engine as my 1990 5 speed manual. Sounds like the 3.4 would maybe be the way to go. Do you know what other vehicles that particular engine would be in? I love the Trooper I have, but it gets to be more difficult to get up the mountains here in Colorado.
Thanks for all the info...
Since yours seems to have come on suddenly, might be something else going on, but it is obvious it needs to be looked at NOW>>>>>>>> before the engine destroys itself. Find a good mechanic even if Isuzu wont help. HTH One guys opinion.
Unfortunately, this is a problem, as I drive the Trooper a couple of hours from home to a mountain cabin, at which point I need the 4WD to navigate the road. I had to let it sit at the base of the mountain, and get a ride with a buddy up the hill. Came back the next morning when the car was cold, and 4WD worked! I have tried this a number of times with the same result - warm - no 4WD, cold - all OK.
Any help would be greatly appreciated.
I used a collet on my milling machine to hold the part while gently filing and scotch briting the part. reassembled, applied power and it now clicks when power is applied.
next step is reintall on trooper. I am running on the premise that if the switch will not function w/ power, the vacuum can't get to the right place. After lunch, I will find out.
All is now well with the Trooper.
Hope yours is working correctly also.
I saw the part on Ebay, $179. I did not check with a dealer. The 4WD engages as it should, hot or cold. While I was at it, I figured this would also be a good time to drain & refill the differentials and the TOD(torque on demand) (thats where the fork slides a gear over the 2 shafts and makes it drive the front wheels) Switched to synthetic oil as we get some cold days here in the Northeast. Responds better when shifted into 4WD.
Not to bore you w/ details but.... the 4WD lever mechanically engages the transfer case and apparently it also sends a signal to the VSV(vacuum switch valve) that moves a diaphragm/shaft/fork assembly, routing the vacuum to the proper side to move that fork in/out of 4WD. I did purchase the shop manual for this rig, hence the long explaination. There you have it.
Glad your trooper works too.
