A question to add to the auto pile: Has anyone had any cooling (overheating) problems with the automatic trans or the torque converter ? How large a tranny cooler do you need, and between a radiator, intercooler, a/c fins, where have people located their tranny coolers ? What is the overall weight difference between a 4L80E versus a T-56/TKO-600? I want to use a Shrifter with a 4L80E on an upcoming project. Is the point the converter locks up completely programmable from a laptop ? With a laptop or other controller can you have multiple pre-programmed shift maps ? How many ? What are the available 4th gear ratios on the 4L80E ? i.e. how large a drop between 3rd and 4th can be put in to the 4L80E ?
Steevo (or Mark Bowler) - how much power CAN this transmission truly handle ? Assume the extreme case of slicks in a drag race environment. Sorry about all the questions but this is a great thread.
