I got my TC installed and have had a lot of vibrations in my car now. I get them when my car is in drive and I'm accelerating. I also get them when the convertor locks up. Any thoughts on this?

Another thing I've noticed is that my car doesn't pull as hard when I punch it from like a 60mph roll. I definately thought that it pulled harder with the stock TC. Is this normal?

I also only picked up a tenth in the 1/4 with the new stall. My 60ft did drop from a 2.2-2.1 to about a 1.9 on street tires. I was kind of disappointed with the results, but the car definately launches hard now.

BTW, I'm running a Midwest 3400 with a 2.0 str.

 

I think the usual advice is to take out the TC-flexplate
bolts, rotate the TC to the next align and bolt it back
up; sometimes this puts things to a better balance
(or not).

Seems like the converter should have done you better
on 60' but maybe you just went from converter-limited
to traction-limited? But too, a lot of crank vibe might
have you seeing fake misfires, even knock retard if it's
bad enough to ring the bell. If you can smooth it out and
it still doesn't get better it's probably time to get some
logging done.

 

your not going to improve on times w/o better traction. However, my car pulls a bit harder on all speeds with my vig. My 1/4 mph was slightly higher with street and slick tires once i put the converter in. Get some nittos or bfg's and you'll be happy with the times
