TH350 what mods make it live?

[muddermilitia]

I'm not a trans expert but I do have a 350 and this is what my trans guy did during the rebuild. Replaced governor gear, vacuum modulator, all new soft parts. My trans already had a shift kit in it but he drilled out a sock plate because he said the aftermarket ones are junk. I believe him due to how bent the aftermarket plate was.

A shift kit is just a tighter spring in the valve body and the plate has some holes larger and some welded shut. That's basically it. You can make your own. In college, my auto trans teacher was a genius. He gave us a printed layout of a th350 and th400 transmission valve body plates. It had specific holes marked to drill out or weld shut. He even made it setup for light, medium, and heavy duty.

If you don't mind me asking,where did you go to college?

/\ agreed generally it is important in cooler climates as the trans sometimes don't get hot enough to flash off condensation. If you don't make repeated short trips and don't have cooler temps you should be ok with just an auxiliary unit of decent size.
Now about that PS cooler.....

I was just having this conversation last night with my trans builder

Hi Guys,

I am swapping to a 2wd th350, the unit I am getting is recently rebuild (stock) and has low miles behind a stock 2wd k5 that wasnt ever beat on, so I know its "fresh" I know the guy and I trust him.
I ordered my converter 2200-2400 stall to match my possible cam choice.

I was eyeballing the transgo 350-1-2 or the -3 reprogramming kit.
I read some stuff about sprags?? No bueno on the stock one for engine braking?
I got a decent cooler, (stacked plate, 11x8x2.5) not using the radiator either.

This has a slip yoke and a 9 inch tail housing.
If possible id like to stay out of the inside.. I can get a th400 but hadn't planned on that for a while..

Do you know when the trans was rebuilt if the low-reverse, forward and direct pistons were machined down enabling
5 clutches in those positions.

I highly doubt it was machines to allow more clutches. The rebuild was a basic stock deal. I might find differently once I open it up though..
