ssglass Posted January 27, 2005 Report Share Posted January 27, 2005 installed billet servos and 3000 stall, havent got retuned yet, it feels like the motor cuts out for a split second and then shifts. is it hitting the rev limiter because of the stall or is it something else. gotta call bryan and get retuned this week.

I can't get it to do it consistently but it is as if I hit the rev limit, then it shifts. Quote Link to comment Share on other sites More sharing options...
zippy Posted January 27, 2005 Report Share Posted January 27, 2005 that's fairly common with a higher stall. very fixable in the programming. Quote Link to comment Share on other sites More sharing options...
BenKey Posted January 27, 2005 Report Share Posted January 27, 2005 Where are you shifting at (rpm)? Mine used to do it if I was at a slow roll, then punched it. Never from a dead stop. I set my rev limit 300rpm over the shift point and haven't had the problem since. (when my truck was running, that is ) Quote Link to comment Share on other sites More sharing options...

I guess I need to get with Bryan for an update. Quote Link to comment Share on other sites More sharing options...
ssglass Posted January 28, 2005 Author Report Share Posted January 28, 2005 i have only noticed it at wide open throttle. i'm not sure what the shift points are exactly,although they are up there flerting with 6000. i have only tried it twice since the install. dont want to break anything.

ssglass Posted February 13, 2005 Author Report Share Posted February 13, 2005 ok, i got my pcm retuned from bryan and the shift delay is still there. i have a small delay from 1-2 , but at least a 1/2 second from 2-3 ,my tranny mods are tci street fighter stall, billet servos, boost valve.i did forget to tell bryan about the boost valve install. i also have a noise around 1500rpms at cruising speed, with foot barely on pedal. dont know if related.

ssglass Posted February 13, 2005 Author Report Share Posted February 13, 2005 no shift kit. i'm considering taking out the t.c. if that is whats causing this problem, or will adding a shift kit fix this? thanks Quote Link to comment Share on other sites More sharing options...

ssglass Posted February 14, 2005 Author Report Share Posted February 14, 2005 may have to try the shift kit. 1st to 2nd shift isnt to bad,but 2nd to 3rd is about a 1/2 to a full second at wot. at partial throttle everthing seems ok. should i go with the transgo hd kit? thanks Quote Link to comment Share on other sites More sharing options...
RacerJJ Posted February 14, 2005 Report Share Posted February 14, 2005 I went with a TCI 2600 stall, billet 3-4 servo, corvette 1-2 and 2-3 servo, and the Transgo HD2 kit...I LOVE IT!!! It is the best mod I have done to my truck. Everything shifts great and I picked up a full second in the 1/4 mile. I would highly recommend the Transgo HD2 kit.

nativetexan Posted February 15, 2005 Report Share Posted February 15, 2005 I have a stock VHO. I encountered the exact problem when I got it tuned. After some "street tuning" we were able to eliminate the 2-3 shift problem by bringing the 2-3 shift rpm down from around 6100 to 5900 where it is now. The 1-2 shift is currently shifting at 6000 rpm and has that annoying pause to it. We messed around with it for awhile and improved it somewhat, but could not eliminate it. (Yes, I have a good tuner) I plan to install a stall, s/k, acumulators, servos and longer servo shaft soon. There has been some discussion on LS1tech.com about the longer servo shaft. Some of the guys are seeing there pause go away with the longer shaft. You may want to try that. Good luck. Quote Link to comment Share on other sites More sharing options...
