Th400 Build.
I am rebuilding a Th400 with rmvb and trans brake and I am wondering what everyone is doing to to strengthen the center support. I've looked into case savers, but I was curious if there are any other options.

I always make sure that the area where the support is bolted to the case looks good. I have seen where the support actually wears the case and it will make a knocking sound while not in first gear. I personally can not remember ever seeing a case saver for a th400 so I'm not sure what you are talking about there. I think the best thing to do is make sure you adjust the rear and front end plays of the unit. Also make sure that all your bushings are good and tight. Vince

A little tip for setting your intermediate clearance, you can use a fwd drum snap ring from a torque flight 8. They are selective, and come in different thicknesses.

i am actaully the one building this th400 for the car. and the problem we have run into before on several RMVB with t-brake setup. well. the brake dont hurt anything. the problem is there is a pin that gives max line pressure causing a sudden hard impact. well on every unit i have seen before that is like this. all the tabs in the case break off and causes intermediate clutches to move freely. i didnt know if anyone out there has ever drilled a case or anything to fix this problem. if so please give some tips. i have a clue what to do but its alot of mods

i beleive i found out how to reinforce it after i studied the case for a while. it will require the case being drilled at least 2 or 3 holes. which bolts will go in to hold a retainer plate to the snap ring and steels in the intermediate clutch. i beleive we can do this becuase RMVB setup do not use a band. and that will give enough room for anything to be reinforced

I would also recommend restricting the converter feed circuit if using a transbrake valve body, or you'll be putting a new thrust bearing in the engine.
