Thanks for the reference Levi :)

Like he said, I have had my tranny rebuilt a couple times as a result of full throttle shifts. Once was because the 3rd-4th gear synchros became too damaged to allow any shifting of the tranny. They grinded for 3 months before it became inoperable...I was beating on it the whole time, though. The second time I snapped the tranny mainshaft right where it enters the diff...not pretty.

I could blame the clutch somewhat for break number one because it couldn't disengage fast enough. Axle hop is largely responsible for number two because it weakend the shaft. But, I know my driving is really to blame.

I practice hard and fast, full throttle shifts even on the spray. I have been able to run with some really stout cars as a result. I prefer a respectable run over a perfect driveline. It really is worth doing if you want to know what you and your car are REALLY capable of doing in a straight line.

I think that it's only a matter of time before something is damaged from powershifting our cars. There is so much mass that must be shifted because of the rear mount/torque tube arrangement. I am very impressed with the T-56 as it is. In the old days, trannies would explode/shatter gears everytime I broke one. This caused a lot more damage and made the drive home and to the shop a complete nightmare. I have yet to hear of anyone shattering a gear in a T-56.

:D

 

jschindler, C5Cemo....did your warranty cover the broken trannies?

 

Swish- I don't take my car to a dealer for anything. I'm lucky I've got MTI for these types of repairs.

I do have a friend who tweaked his tranny in his bonestock '01 Z06 and it was covered under warranty. He had to go back once to get everything right, though. They did not reassemble the rear carrier perfectly which cause some suspension noise.

 

How about twice. I'm on my third trnny and each one happened from powershifting with a hot clutch. Not a good combo.

 

yes. Probably would have anyway, but I have a great relationship with my dealership. I've bought eight cars there in the last seven years, I drive about 40 miles - past probably five other chevy dealers - to get to them. My loyalty pays off. Doesn't hurt I am on very good terms with the owner.

 

Powershifting = Damage to the drivetrain/tranny resulting in loss of $$$.

The best "Bang" for the buck is to up the HP, not powershift. Then again, if you want to get a "Bang" out of your Vette then go right ahead and Powershift all you want.

:cheers:

 

HOLY CRAP! You guys can shift from 1-2 or 2-3 with your foot firmly planted on the gas and it only goes up about 100 RPM? Sheeee-it! No wonder you don't bounce it off the limiter... :cheers:

 

I USED to go 200 rpm below redline when I shifted. It is not a problen but my C4 had 4 transmissions is it fun yes but it gets expensive. I raely did it in my C5 only a few times in a close race.

 

I am with the powershifting crowd here. i do lift the gas ever so slightly when dragracing, only to turn off the nitrous while shifting. Like said above, it happens so fast its like the quick draw of the west contest. i am surprised i have not bent my shifter linkage by now!!! My best times are only with PS'ing.

 

Ok, I guess I was wrong about what "Powershifting" means... here's what the Ford Guys say it is...

I agree with the description on that link. I don't think the really good shifters see anywhere near a 500 rpm rise though.
