Stall before cam and tune?
Stall before cam and tune? Can I run a yank ss4000 before I cam the car? I'm looking at running a ms3 or 4 in the future... Also will a frost tune do for the stall until I cam the car and get it dyno tuned? Thanks
trans tune does a lot for these transmissions, especially after installing a big torque converter. my car basically wouldn't shift 2-3 unless i let off the go pedal before tuning. be sure to get a transmission cooler when you install a larger speed stall converter.
shift kits are easy to install, i recommend transgo. they have step by step instructions and i think even a video now, too. shift kit was the first thing i did after purchasing my stock 2000 a4 car that had 38,000 miles on it. i installed the shift kit, 4k stall and had the trans tuned somewhere around 40k miles, made hundreds (literally) of 1/4 passes, sold the car 50k miles later. as far as i know it was on the same **** when the guy who bought it off me sold it again haha.

With a bigger torque converter you get more slippage, meaning the input rpms does not come out of the torque converter like stock. Say you input 2000 rpms into a stock converter you may get 1800 on the input shaft of the transmission. With a 4000 converter, that same 2000 rpms from the motor may only turn the transmission 1500 rpms. The computer will pick up on this and likely throw an SES light because the computer thinks it's possibly a transmission failure. Also, by having less rpm going into the trans, you get less mph, and since shifts are calculated on mph and rpm, these tables will be really skewed with a big converter. That's the point of having the "trans tune" done. It will allow for slippage when dealing with fault trouble codes and transmission shift table. Another thing is big converters make the trans seem like it is shifting very soft, and I personally like to give it a little more pressure during upshifts so they feel a little firmer. I like this on even the stock converter as well, because I don't think these transmissions have a "solid" shift feel when they are stock.

Flexplate is what connects the crank to the converter. A plate so to speak that will flex a little as the converter moves under load. You already have one, but they have been known to crack. So upgrading to an SFI rated one is cheap insurance.
