High rpm c;lutch slipping or wheel spin

**01z28425** · 03-18-2010, 09:53 AM

Hi. Just got an 01 Z. 425HP at the wheels. When I shift into 3rd gear under wot the rpms zing to redline from about 5500 up. I cant tell if the cluth is slipping or the tires are spinning. Clutch works and performs great with no smell and no noticable slippage any other time. Any suggestions?

Well let me ask this...Are you spinning and redlining going into 2nd? If no, I think you have your answer as to whether it's your tires or not.

You would certainly be more susceptible to spinning the tires going into 2nd than 3rd so if you're not spinning in 2nd the chances of you spinning in 3rd is nil.

425rwhp is certainly enough to get the tires to spin good shifting at WOT. What do you have done? H/C/I? How many miles are on the car? Stock clutch or aftermarket?

I just got the car the other day. It was a repo so I was not able to speak with the previous owner. I am not sure about the clutch I know factory they come with the ls6 clutch in 01. The motor is built, cam, headers, tune, ram air, 3" true dual exhaust, 12 bolt mosier rear, street tires. No spinning in second at all. The only time I can get it to do it is when I am shifting into 3rd hard. No smell. The motors revs up so fast in that area and the car is really loud so it is really hard for me to tell. I figured if the clutch was going to slip it would do it throughout the powerband and just not in this rpm area.
