Maybe it's the age thing I was a week from swapping out the tranny and transfer when I found the gov. was bad in my TH350. I was having some pressure problems in third gear. It would just go into neutral like mode while cruising down the road in third. I was stumped as to what the problem was. Someone on this site mentioned the gov. along with the modulator, and a host of other idea's.
For that, I'm forever grateful as I still have the rebuilt tranny siting on the floor collecting dust! I was planing to try the engine hoist through the passenger door thing through the hump on the floor. I remember lifting it out of the truck when I bought it and it seemed to have a close balance with a strap around the tranny tail and the transfer.

|BBCMudbogger||It aint that bad sqz...I use a tranny jack an strap the transmission tight to the jack....in and out no sweat...change one in just a few hours. The 350 will be fine. To go to a 400 you'd have to get a transfer case with the right input and the right adapter but I think there are holes in the frame for either the 350 or 400 crossmember location but it ain't hard to fix that.|

its good that you said to use a stock converter because it turns out that i called lunati and they said my cam can be used with a stock torque converter.
The reason im wanting to change trannys is becaue the one in it is a stock th350, and the engine is making more power than stock and the fluid is still red but with some black in it. i think the more power from the engine is burning stuff up in there. i dont know the diffrence between the th350 and th400, is the th400 better? and if it is, how much do i ahve to change to install that rather than the th350
Also the tranny is cooled by a 4 core radiator and i also added an aftermarket trans cooler that sits in front of the radiator.

If I were you, I would look into a shift improver kit. With the towing you do, a high stall converter is going to build a lot of heat and will need a GOOD cooling system to keep temperatures down.
Your also looking at a lot of work! I'd rather pull 2 engines than have to pull a tranny with the transfer case. The transfer weighs a ton and in my opinion, is a pain in the butt.
Unless you have the money to get someone else to do the work (which is the easiest way).

me personally i'd use a th400.. but the th350 will work.. as for a converter... just use a stock one. that would be around 1500rpm unit. u don't need one in the 2000+ for normal use.
