Slipping rear end?
All right, here is the deal. 1992 GT 5-speed with new clutch.
Anytime I bury the accelerator around 2200-2500 RPM, no matter what gear or how fast I am going, it sounds and feels like the tires break loose. Now I know in 1-2 gear it may be happening, but when I am cruising on the freeway at 60 in 5th gear and nail the gas, the engine speed picks up WAY more than the car's speed. Not so much like if I pushed the clutch in, but more like something is slipping. Kinda like an automatic trans. that is slipping would do.
Any ideas?
Car has stock 3.08 gears and a stock engine with just a Flowmaster exhaust system..

my car has been doing the same thing in a way. I can barely get on the gas and it revs up and won't go any faster. Then I can go slam on the gas and spin wheels to 70 mph.
I thought it was a clutch slipping. The rear-end does make some weird noises and is peg leg most of the time.
When the radiator comes in this week, i am going to make a day of it and try to fox everything with help in a day or so.
I will ask the mechanic if the rear-end slip is possible and causing the slippage tomorrow.

Thinking there is some oil or something on the clutch. I just had an oil pan put on it, and the idiots might have gotten some stuff on there. Will see tomorrow...
I hate having people work on my stuff. I NEED MY GARAGE BACK!

There's a thin steel plate seperating your rear main seal from your flywheel. Then the flywheel shields the clutch from the oil.
Your clutch is slipping. Out of the countless cars produced with open rear ends none of them have issues that you are describing. Unless you have serious power your only going to be doing the one wheel peel in first and maybe second gear. Unless you are in the rain or snow.
I think it's time for a new clutch.

It is physically impossible for a rear to slip.
Yes, the clutch packs may let one wheel spin under acceleration, but the ring and pinion are big hunks of metal that can never slip. Either the teeth on the gears are sheered off and the car will not move... or they are intact and 100% of the power from the driveahft is tranferred through the diff to the wheels. There is no in-between.

agreed^^ and check if for an oil leak thats getting onto the clutch somehow.
