The TEP shift kit is really easy to install. It doesn't require any more disassembly of the transmission other than the tranny pan and the accumulator housing. There isn't much in either of those that you can break.

That should help you understand the installation.

Good luck! and i completely understand apprehension to doing major work on the car. It took a while before i felt comfortable, but not i'm much happier knowing the work got done by someone who cares (myself).

ferb!
