Input on my Vette, Best way to fix my down shift problem. New Stall Maybe or Gears?
Hey all:
Well here is a quick run down.
I have a C-5 Vette fully built and stroked, full exhaust and had a new cam installed a few months back ( went bigger ). It has a fully built stage 5 trans with a Pro Torq 2,800 stall and 342 gears.
I have a dead spot from 35MPH to 50MPH. Under 35MPH and over 50MPH it comes unglued but between 35MPH to 50MPH its a dog.
I was thinking maybe a bigger stall like a Yank 3,400 or 373 Gears.
I am kind of lost here and dont want to waste money if it wont help.
Thanks

A bigger stall would help. Yank recommended me a 3600 stall with a similar setup tp yours.That would help but you can tune the tc clutch line pressure as well to help with lock-up as well as tune shift time and shift speeds. 3.73s would help to but I have 3.42s with a 3600 and I like it. Get the Yank first, if you want then add gears. Youre gonna get the tc anyway. Good luck.

the car doesnt seem to have a "dead spot" when i drive it, it has normal areas that it is out of it power like any other 4l60e with a relatively tight converter, if i change it any more it will downshift then shift right away because it will be at nearly redline when it downshifts... my suggestion is to a higher stall converter that way you will be in your powerband more often... this is the problem with the wide spaced gearing on the 4l60e it needs a good stall to be in it powerband at all times. i suggest a yank 3600 for the nitrous or na a even 4000

I was staring to really think it had to be the stall. All My cars have been manuals and this is the 2nd auto I have had.
I keep comparing it to my old 02 Camaro that was H/C/I with 342's also but I had a Yank 3,200 and it had really no dead spots. Plus the cam was way smaller in the Camro compared to my Vette. It was a 224/224 on a 114lsa.
So my next question is: Ryne PM me on what you can do for a Yank 3,600 set-up for Nitrous and installed. I will be looking to do this after x-mas.
Thanks
