I bought a 5 clutch direct drum. It looks like it was a 3 clutch. So when i put the clutches in, i have way too much clearance. I dont have a wave plate so that might be why. I have thicker snap rings but the groove is too narrow. I can only fit an 085 the 095 wont really go in. If i add a steel to the bottom the friction disk will slide into the old groove. Is this a inproperly made drum or is that ok. Will the ring gear hold it out of the groove?

What clearance have you got ? What combination of frictions and steels?
You can get O/S steels , std is .078, O/S is approx 094"

I was just dry fitting everything but like 095 with the 075 snap ring. using 5 alto red frictions and 5 steels @ 075 each. If i add an extra steel or a wave plate or oversize steels it will raise the last friction in line with the old snap ring groove. Its just below it now. Not sure if that will be a problem.

Ok way too much . Assuming you have the stock thickness pressure plate ?

It's not so much that last friction it is as long as the steel stays below that groove

Frank says : "the reason for using the wave in the forward is that with racing line pressures and no waveplate it tends to snap the end of the drum off at the snapring groove after a period of time .In my max effort trannies I leave out the wave and contend with the drum breaking if and when it happens , usually I just put an new drum in each year "

At what pressures does this become an issue? Both wave plates I have on hand look pretty well used. Some builders don't use them at all from what I am finding.

VR3 , who's valvebody are you running ? it could be as simple as a hole in the spacerplate .030 to big , Alot of people building valvebody's don't have a clue about hydraulic's , you could send the valvebody up to me and I could Dyno it in a trans and see what the problem is .

Frank,
I have a 91 F250 300cid c6 that wont go into reverse. 1st and 2nd gear shift fine, to get 3rd, I have to allow the trans. to warm up and shift into Neutral then drop into 3rd. It goes into 3rd with no slippage and will run all day. I disassembled the valve body and noticed the gasket was brittle and a few small pieces missing( like someone had tried to reuse the gasket, also fluid looked good) could this cause the line pressure to be to low to engage the high/reverse clutch, or do you think something else is the problem? The valve body and all the valves and springs look new with no noticable wear. I am new to automatics and any help would be greatly appreciated. Read your posts and can tell you are the man to talk to!
Thanks,
Matt

I'm assuming when doing the Merkl Mod on the TCI VB the channel needs to be cleared, along with the other side.where the epoxy filled in?
