But this is a timely thread. I’m rebuilding a 727 and I was looking at that TF3 manual valve body kit...I was going to not use the kick down linkage....I could have made a big mistake...
Yes, the first TF3 that I did I was unsure so I called transgo and they confirmed that the kickdown (actually throttle pressure) linkage is still required.
I would suspect that the wreck is a result of a really harsh shifting automatic and tight sure grip or spool, downshift or upshift at speed on a corner possibly in the rain and the back end comes out from under.
