That's good info that 60 and 80 can use same settings!

Here's some info to think about. No need to use EEB, just flash with EE, it's worked for me many times. 4L60E from 94 which is only one early in year $EEB to 95 $EE trans is 95 has PWM TCC, there's an exrta wire from PCM to trans and I would guess some bin file changes? I just stick to keeping a bin year to trans. If there's any mechanical mods to trans then line pressures should not be touched as they have already been modified.

Use TunerPro RT to datalog transmission! It is a seperate data logging connection from motor data, this will keep an eye on what's happening like shifts and more importantly tempretures! Can see how MPH and shifts line up, does TC do gear change calcs in bin? this could very well be the biggest issue. There's three speed related settings in bin, start from a stock bin and make the overall changes. I know that TC OBDII does this overall and can bee 100s of changes to all the tables! Have any of these wrong and all sorts of shifting issues and heat can occur.
