Hi how's it going i just joind this bulletin board and have had nothing but success. I am kind of green at this, i have only rebuilt 4 Th350 transmissions and 1 turbo 400 but I have a th350 in my vehicle and i was wondering if you Novices out there could give me some tips and tricks on how to make the transmission shift harder/firmer.
any thoughts would be greatly appreciated

Good luck!

HEY BIG: I put a Transco manual/automatic shift kit in my 350TH, which provides manual or automatic shifting. It came from Summit Racing for about $ 70.00. www.sumittracing.com It comes with video, color coded parts, 800 tech line, backing from Sumitt. It is a great performer......DAVE

I had a B&M shift kit in the transmission but then i was told to try a transgo and as far as i am concerned the transgo was a waste of my money, it didn't make the trans shift very much better than stock, and that was with only 1 check ball, and 4 check balls thinking that it should make a diff but it didn't, so i ended up putting the B&M back in with a bolt in the servo and now it shifts alot harder/and smoother at the same time.

I just wanted to say that was just my opinion on the transgo, but I also searched the site for how to make the trans shift harder and i couldn't find all that much, like drilling the holes in the seperator plate bigger, blocking off the plugs in the side of the case, and putting a bolt in the servo piston on the side of the case, i also put a 2nd gear steel plate w/o the friction material in the pump, which helped. Some more ideas would be greatly appreciated.

Hi Big:
Regardless to what some may say, the easiest fix for firmer and harder shifts is to change over to Ford Type F fluid. You will get alot of different views on this, but works just as good as B&M's trick shift for a lot less money.
