|chevy_phil||Well turns out my crack in the case is a line where the casting molds met and is just cosmetic so that saves me some money but unfortunatley the 400 hd case won't happen this time. I ordered the tci rmvb with engine breaking before I saw your post, hopefuly mine holds up...Also 34 element sprag, borg wagner(sp?) HD clutches, deep pan and extension. The shop rebuilding it will warranty if for a full year even after seeing the truck its going in so thats some peace of mind.|

Not sure why my phone was set to B&W.
|03-23-2012 09:22 PM|
What failed on your VB anyway?

If you are near the city, Toronto, try Transware, Mike 905-660-3650. He helped me with parts and questions for my 400 rebuild over the winter. He has been at it a long time and seems to know a lot but these. Duff/407 area.

|cwaggoner||Hughes performance. Done. Latest 400 started with a tci rmvb w/ engine braking. didn't make it to the trail. 2nd gear started slipping from a dozen full throttle street runs on 42's chirping tires shifting to 2nd. Hughes now is making there own rmvb in house. Call and talk to Tony or Bill and tell em Big Chuck from Flynhi sent ya.|

|Corey Young||1988 motorhome. The newer the better on TH400s.|
|03-21-2012 09:26 PM|
Why is the 1965 (I believe thats the year) so different?
Thanks for the info too.

If you are going to run an aluminum pan, the B&Ms have a thicker flange then almost all the other ones, just put a skid plate on it.
Here is some good reading, there is a ton of info about TH400s on the web, just search around:
These things im pointing to with the stick, I think they are the rear band lugs, make sure they are not working out

I will have a barbed fitting in the breather to my Canton breather/overflow tank
Was looking at cast aluminum pans till now, I will get a stamped steel one
What are those plug things in the side of teh case for?
|03-21-2012 06:02 PM|
A few other upgrades are longer block dowls, the factory ones are short and sometimes the two allignment holes in the bellhousing get worn out. The plastic breather can be replaced with a newer GM metal one so you can attach a rubber vent line, water will kill the clutches pretty fast. There are two roung metal lugs/dowls in the side of the case, make sure they are not backing out, some guys TIG weld the lugs in just to be safe. When you have the case all disassembled, look for cracks, there are at least 6 different places I have found hairline cracks on "good" working TH400s. Motorhome TH400s have bigger cooler line fittings, I think they are 3/8 and most other vehicles are 5/16" diameter. Most HD trucks and motorhomes have factory deep pans and filter extensions. A sheetmetal pan will take a hit from a broken driveline or rock and deform, when a cast aluminum pan will crack and leak.

Corey, This is the trans out of a 2wd suburban where I got my 454, I think it was a 81 3/4 ton so I probably dont have the HD case. Mine is bolt on 1350 yoke. However there is a crack forming off a govenor cover bolt towards the tailstock so I will be in the market for a core.
This is great info to know, Hopefully I have luck finding one of those cores!

|Corey Young||What year is your trans? What was it out of? I start with 1982+ motorhome or CUCV/K30 cores, they have some factory HD parts to start with.|
|03-21-2012 03:29 PM|
|03-21-2012 08:30 AM|
Have you looked at this?
|03-21-2012 08:22 AM|
Is a deep trans pan and filter extension worth while for the money if I have that cooler set up already?
|03-21-2012 08:13 AM|
|greenlion||RMVB, 34 element sprag and good clutches will do it. Use enough cooler and a decent converter.|
|03-21-2012 07:11 AM|
Also and upgrade for the planetaries as well...
Now that was 20 years ago when I worked in a transmission shop but there is a company called AutoStan that used to supply parts to the location I worked at and at the time they were very helpful in purchasing the transmission parts that anyone needed.

|Aisin||Wow, another TH400 rebuild thread. Between Gen. 4X4 and the Chevy forum this comes up three or four times a week.|

Th400 rebuild time...
Well I have to rebuild my th400 before this season for sure, was hoping to get through a year before building it but that won't happen so might as well do her up a bit I want it to handle what I do and last, but without breaking the bank
Going in chevy k20 with healthy bbc(400+hp) and a divorced 205 case, tons,tci saturday night special stall for the th400 , 44 boggers ,etc..
Called Rossler transmission and they are booked for 8 weeks so I am going to the local mister transmission Just hoping to get kinda a list together of what I should make sure to tell them, or parts to use, etc.
I want to have P,R,N,1,2,3 shift pattern instead of the old P,R,N,3,2,1 and I will not be using the kickdown and will always manually shift it. So I think a TCI reverse manual valve body should go in there? Oh yeah and they have 2 of them I see on summit, one with engine breaking, I assume I want that one? (i like my gears slowing me down)
Should I ask for a high flow pump?
Mister T guy said they will use extra clutches and can do a few other things but wasnt very specific... So I wanna know what I am talking about for when I bring the trans over and talk to him about what I want tomorrow.
