Question about 1992 Isuzu Rodeo

New clutch still slipping

New clutch replaced by a national shop.

It doesnt happen at cold temps... only after warmed up. Easy/slow driving everything works fine. Try to accelerate in any gear and the clutch slips. The clutch peddle is never ridden. Because of this I've become very conscious of my clutch use. But it doesnt seem to matter what I do differently. I'm perplexed as to why the temperature would have so much bearing on the clutch performance.

Adjustments have been made a few times. No one can seem to diagnose it. Any ideas?

Was the flywheel ever re-surfaced? it sounds like the pressure plate is not squeezing the clutch disk to the flywheel good enough for the weight of your vehicle.

There are a few reasons why that could happen, either there is oil contamination from the engine or transmission leaking oil and it is getting to the clutch disk and pressure plate, the throw-out/release bearing is riding the pressure plate and not allowing the clutch to fully release. (could actually be the wrong clutch assembly for your application) The flywheel was not re-surfaced or done so properly, a lot of wear will cause a dip in the surface of the flywheel, causing a lip to form around the outer edge of the flywheel, and this area is where the pressure plate bolts to the flywheel causing there to be a gap between the pressure plate and the flywheel, and this space will not be made up or taken up by the pressure plate in any way at all, which means that the pressure plate is not going to be able to press the clutch disk to the flywheel good enough to hold the weight of the vehicle.

I used to re-surface flywheels and there are some step flywheels with a raised lip on them and the clutch disk actually sets into a dip or depression in the flywheel, but those flywheels are designed to work that way with that type of a clutch pressure plate, and when those stepped flywheels are resurfaced the stock height must be restored between the lower surface of the flywheel and the ridge where the pressure plate bolts to the flywheel for proper clutch operation.

Always make sure when you replace your clutch that you get a good quality complete clutch assembly set/kit, including throwout/release bearing and the pilot bearing or bushing.

I hope that this information was of any help to you.

Check your fluid level first. Is it low? Is it high? Either canose a problem. If it drives fine in 1st-2nd gears but is slipping in drive it can be several issues. first try draining the fluid, flush the system with clean fluid, may have service shop do flush, and replace the filter. This is the least complicated and least costly repair. If this doesnt fix the problem it sounds like your forward band may need adjusted, or replaced. depending on the transmission design it may not be adjustable. If it needs replaced, I suggest either buying the rebuild kit, around 300$, and replace all 3 bands and all clutches since they have to be removed anyway, or replacing the transmission, new up to 3k/used 50-500$ but no gaurentees it works

Try and clean the throttle body. Carbon will gum up on the blade and the vaccume passages, which will cause a surge and stall.

1986 dodge ram 150 tranny problem


Sorry this is not an easy fix the clutch packs in the transmission are slipping, usually caused by wear, but the hydraulic pump is probably getting week. As the oil warms up the oil gets thinner and the hydraulic pressure decreases. Times for a overhaul of the transmission, and if the torque converter can not be flushed a new torque converter is recommended. You may get lucky buy changing the fluid several times, but if the transmission is 22 years old it may not help.
