904 Recommended Parts For Rebuild

[Wedgeamacallit]

Hello all,

I am in the process of getting parts together for a 904 small block rebuild with about 400hp. Car will be mostly street use with some track time but not much. Trying to do this on a budget. What would be the must have parts for this application that would not be in a stock style rebuild kit? I am going to use the Trans Go TF3 manual shift kit. Thanks for the help.

Start with a A999. It has a much heavier duty geartrain.

Get whichever Cal Deluxe kit with the band that you need. If you need steels order them further down the list. I use these guys all the time. Just installed my 1st TF3 Kit. Why are you use the TF3 instead of TF2? Used a bunch of TF2. They work very well.

Thanks Doug. I will check them out. I have always used reverse manual valve bodies so I decided to try the TF3 since it manual also with standard pattern. Just trying to save some money over buying a valve body.

The TF2 allows full manual operation but retains auto shift. The TF3 either requires the TV valve tied back/or some method of holding it all the way depressed. You could probably weld a washer to the bottom of the TV shaft that was large enough diameter to keep the valve depressed. When I talked to their tech guy he suggested still running throttle pressure linkage. Said it would engage softer at idle. So thats what I did. The car is just being finished now so it won't get any road time until spring.

I will either tie it back or do a type of bushing to limit the travel.
