well i just picked up my first truck and i already have alot of questions...first thing is it being used i really have no idea whats in it...350 with carb maybe mild cam. sounds good runs good. but it has a th400 tranny in it which im not crazy about, i feel like my motor might not me up to par..is this something i should change, for a 700r4/th350 or something. any opinions appreciated. other than that im gonna start a project thread with some pics when i get home tomorrow. and go from there!!

What is wrong with the 400? if it runs good and drives good, what is the problem for now? I would drive it and do/plan small upgrades, saving for the big ones along the way.

If you take it off the street now, it is entirely possible to loose interest faster and then sell it and we all know we dont want that.

very true..plus i was just looking at the 700r4 swaps. and i feel like its a diff language ..new flexplates, shortened drive shafts, moving crossmembers..i dont know if im up for that right now..i just heard that the 400 with a stock/mild 350 might be to much..but if its not that big of a deal ill jsut keep on rollin..

The only downside I can think with a TH400 is being big and heavy. But it's also bulletproof, a very beefy and durable transmission. Granted it doesn't have overdrive, but the need for O.D. needs to be considered along with tire size, axle ratios, and what you intend to do with the truck. I'm with Clyde65 use it for a while to determine what you like and don't like, then formulate a plan (on paper) and start applying costs to the different options before you make changes. Too often impulse decisions can derail the entire project.

good advice guys..thanks. and thanks in advance for all the questions your going to see shortly from me!

**Clyde65** · 11-22-2010, 05:07 PM

Scum1,

I had a 400 behind my 350 for years, never gave me 1 inch of trouble, even when I was beating on it and beating on it, it came back for more....more than I can say for the 350 though.

Scum,
I had a 400 behind a 283 in a hotrod for years. I tried and tried to blow that truck up cause I had a 327 waiting for it. I never did but the tranny never gave me any problems and always shifted strong. If you want OD then I say change it but if thats not a concern drive it and enjoy.

scum1 · 11-22-2010, 08:02 PM

right on..thanks guys now im gonna post another thread on something i just noticed that im not so happy about maybe someone could chine in as well.

Apparently, there is something about your transmission that bothers you. Could you be more specific and tell us what it is doing that you don't like?
