Is my Torque Converter screwed? I went to the track Friday night for the first time since my 3.73 gear install. I noticed that I was shifting from 1-2 around 35 at redline, 2-3 at somewhere around 50-60 at redline and 3-4 at exactly 82 and was hitting the rev limiter. I reprogrammed the shift points from 3-4 up 3 MPH and it shifted w/o hitting the limiter. From my post below I was told that most likely my torque converter was acting up. So is that what it sounds like? I just committed to buying a TP4400 from another guy on this site. What else should I buy to help the trans handle this torque converter and how difficult will the install be?
Re: Is my Torque Converter screwed? You should not be shifting to 4th with 3.73's in a 1/4 mile. I have run a ST3500 with 3.73's on 26" tall tires at 109 mph and never shifted to 4th. I think your gear/tire height settings are screwed up with the HPP3.
Re: Is my Torque Converter screwed? This may sound like a stupid question, but are you sure the shop put in 3.73's and not 4.10's? A4's finish the 1/4 mile in 3rd with 3.73's. I've never seen one, but I've heard that A4's with 4.10's will shift into OD before the end of the 1/4 mile. That's the correct tire height for stock tires.

Re: Is my Torque Converter screwed? What year car is it? I've seen posts where early HPP3s don't get the gear change right w/out some tire height "tweaking". Not sure what years, might be 99? Try this link or search for "fuzzy math" in this forum.

Re: Is my Torque Converter screwed? dude, that's wierd. I shift from 1-2 where you shift 2-3!!! I've got 3.23's but still, for that gear change, I can't see the car changing that much

Re: Is my Torque Converter screwed? He is running 1/8th mile guys. Wes, the car should be barely in 3rd in the 1/8th. That is the reason I looked at you funny when you told me it was hitting the limiter on the 3-4 shift at the track. You should be going into third about 100' or so from the traps. Good luck figuring it out.
