I am going to do some work on my '87 Jimmy 4X4 2.8L soon including the clutch, transmission and engine performance parts. I searched through the old posts but didn't find all the answers. Here's the deal....
First, I think it is time to replace the clutch (60K miles on it) because it is catching at the top of the pedal and may start slippin' soon.
Which clutch would be good? Performance? Heavy Duty? What are my options?
Second, I think it is time to replace the trans (130K miles on it) because it has a 5th gear synchro problem and possibly other problems abound in it. I heard it is cheaper and, of course, easier to just replace it instead of rebuilding it
It was suggested on a post by "355S-10" to use a NV3500 trans instead of the Warner 5sp. Are these the only trans available? What are the key differences?
Third, which TBI replacements can fit on the 2.8L engine? I know Holley has one for the 2.8L. Is it possible to use the ones by Holley that fit the larger engines without modifications? Or others not by Holley?
What I am trying to get at is that since I am going to replace the clutch and trans, I don't want to install something that will not be able to handle increases in horsepower or torque, if those become a factor later on (performance TBI, etc.).
In case this helps I am using LT235/75/15 tires, the engine is new and has only 50K miles on it, off-road & towing are involved. I also rebuilt the clutch slave cylinder recently.
Thanks in advance for any advice you have.
