Transmission upgrade

[skysix]

Has anyone swapped the stock th400 in a 1031 (or equivalent) or a current generation heavy duty manual transmission? How well did it work out?

If you do a search for nv4500 you will find more and also on pirate.

Having owned a few civy 6.2 s with manual trannys, I would advise you to stick with the TH400. the torque curve on the 6.2 favors the automatic, unless you are going to put in a 5 or 6 speed. The standard Chevy 4 spd w granny gear works ok w a gas 350, not so much with the 6.2. It is likely that the crankshaft was not bored out for the clutch pilot bearing, many 6.2s were not.

a nv4500 is a 5 speed......

What TH400 characteristics do you want to improve on?

My first guess would be overdrive.

Try to do a little searching of the site. Many questions have been addressed.

Thanks for the NV4500 link - now I have an idea at least of what trannys might work! Will make searching a lot easier - which was the plan once I found out if anyone had already done such a swap.

I just hate auto's - especially in ultra cold weather. Have used the SM465 and agree - not well suited as-is. The overdrive gear would be easier to use if built in vs an add-on component and I am planning to add a Banks Turbo.

Thanks for the nudge in the right direction!
