Beefing Up 904

Aaaaah yes, TCI.
About 20 yrs ago I bought a TCI o'haul kit for my 727. Also came with TCIs shift kit.

The shift kit instructions were photo copies...very poor when you need clarity.
But worse was to come.....
As I read the instructions, they seemed familiar.......
I got out some old Transgo instructions & the TCI was a copy, just the odd word changed here & there to make it look like they were different.
Agree with other comments about usage. A Transgo shift kit, plus possible upgrades depending on usage.
