Has anyone gone non lockup in there syty? Why did you do it?

Should a non lockup last longer?

What are the advantages and disadvantages of a non lockup?

Will I hurt my trans if I run it unlocked when I race it?

TIA

A non lockup TC will really hurt your mph and you'd better have a pretty stout cooler on that tranny, they build a ton of heat.

Problem is getting a convertor that is loose enough to spool the turbo nice at the bottom and still be efficent enough at the top so you don't waste a bunch of rpm.

I'd stick with a lockup dude.

Roland went non lockup, as well as Paul (another WA member). Both are not overly happy, I think Roland is somewhat ok now, once stall was fixed, but Paul isn't fully.


I would heavily suggest staying lockup.

So what was the outcome, verdict on tranny failure?

If you had a manual transmission would you want the clutch slipping all the time? Then why would you want it with an automatic?

So why do so many of the fast Buicks run non lockup?

I don't know. I've never really put a lot of thought into it to be honest. I suspect it may have something to do with keeping a modified motor revving higher in it's peak power range. Loading things up locking the convertor works for me. But maybe in a cammed car making more top end power the extra rpm works well. Still losing HP through slippage though. Try a search in TB.com if you haven't already. I'm sure the answer is in there. ;)
