Transmission "Tuning" for Circle D 2800? Doing a rebuild on my buddy's 4L60e for his '94 Trans Am. The car is just bolt ons for now, but he may be doing a 100 shot next year.
He wants to upgrade the converter while it's out, and is looking to spend about $400 on a stall. We're looking at the GM 298mm HP 4L60E LT Torque Converter from Circle D (2400-2600 stall). I know most people reccomend 3500+ stalls, but he's not looking to spend that much on a converter-he just wants a little affordable upgrade while still using a reputible company/product.
Anyway, I know in the past I've read of some people needing to "tune" the transmissions after putting a larger stall in. What would this entail, and would this be neccessary on a "2400-2600" stall?
Thanks!

In a 94 car the shift points have to be changed in the computer and that requires having someone tune his computer or getting the tuning cable and a tuning program and doing yourself.

Gotcha, kind of what I figured. I've done some reading up on it and realize that every car can be a little different, but would a 2400-2600 stall be easier to tune/get correct shiftpoints compared to a 3600+ stall?
The reason I ask is because we will likely be doing a mail order tune, and would like to minimalize the shipping back and forth part as much as possible.

I wouldn't consider buying any quality torque converter a waste of money really. There is better bang for the buck out there, sure, but this route is worlds better than slapping in a cheapo parts store converter. I stated the reasons why he is going with that size of a converter. What "badass converter" would suggest for $400?
Testimonials on here show Circle D, Yank, and Vigilante are tried and true companies with great reps and consistantly performing and quality products. He's looking for a quality one that will last for years and be consistant, not the highest RPM for the cheapest amount of money, but maybe we missed something somewhere.
I am also suspecting that the higher the stall rpm, the more time it will take to get the shift points tuned correctly, though I may be wrong-still waiting on confirmation of this. He will be going with a mail order tune, so the more times it needs to be tuned, the more downtime and shipping costs. Just trying to consider things from all angles here.

Well, he ended up ordering a Yank 3,000 stall and got a great deal on it, should be here next week. The guys at Yank have been awesome to deal with thus far he said.
Tranny should be all ready to go in by the end of next week, hopefully installing it next weekend. Now we just have to see how the transmission performs when it's all in and buttoned up, contact a few different mail-order tuners, and go from there.
