U think I have a china made sun shell so it could save me a little money being that I have to replace the drum the 2-4 band rides on?

I might be an older Beast Even. I'm not sure of all the different markings. I've not heard of any problems with China Sunshells like I've heard with China 5 Pinion Planets. It certainly isn't the OEM Weak GM unit, so worse case sneraio, it is a China hardened upgrade unit. Again, I've not heard of any issues. So yeah, you're probably OK to run that Sunshell. It does look much more beefy than OE for certain. You have another 700r4 core don't you? Maybe you can pull the drum from it and see what it looks like.

Ahhh, OK. So what you're saying is, this current build is going to be an ongoing project as time and funds permit. A piece of advice, especially for a new builder, or even a builder on a new model can be even worse since he can get mixed in different models in his head, BUT !!!, when you do them this way, you tend to lose parts, forget exactly how things go back together etc. Luckily, you took pics and hopefully shitloads of them. This is one reason why I don't even start my builds. I wait til I have EVERYTHING I need, with exception of the unforeseen like that drum for example. But, sooner it's back together the better.

And I might be worse than others, cuz as it sits right now, I've got 4 different transmissions tore down, on 2 differnt side by side building tables. It's a good possibility parts could end up in different transmissions doing that. And normally it's no biggie, but what about when 1 part is just a tad thinner than another, and the selective thrust washer has been calculated for the build. Now you might have to get aother selective washer or your end play might be off. Always go back with the original parts that came out when you can. And if you do swap, be prepared to make sure they are compatible with all the other designs of the hard parts in the build. Example, swapping rear sun gears in Th400's might mean you also need to swap the parking pawl. If you didn't grab the parking pawl from the donor trans, good luck finding the right one.

Yeah, you should be OK. I wish I had a 700r4 apart to know if I have a spare drum. I'd send it. Have you priced any used ones yet? If it's to crazy expensive I might have an 84 trans I'll pulling apart cuz I think it's got the BEAST in it, and I want to use it for my build. I'd have to make sure there were not changes in the that drum too. But I might have a good drum in that 84 Trans. I just hadn't planned on pulling it apart anytime soon, espeically moving and having to box up trans PARTS and marking them all. I"d rather just keep all the trans together.

That didn't take long. My book clearly shows the 87-92 is different and NO, I WILL NOT seperate my good 87-92 cores. I do believe this is what you need. Flip yours over and compare the pics. Pretty sure that's the one. But not positiive, so check it out.

This guy is a bit cheaper, but his used. The other guy claims his is refurbed which is probably just ground down and smoothed out like turning a brake drum. This would mean your Servo pin has to travel a bit further for a tight clamp with the band. The used is better really, IF it's a very good used and isn't wavy where the old band was riding the drum. And if you're going with a wide band for more clamping power, then by all means go with a new drum cuz it will wear the band fast on the surface where it never had a band before, and by the time it caught up with the center of the band, the outer portion of the wide band might be burnt up and spread to the center. This is is wny things like a wider band are not always better and why it's important to know what parts do what and how they function. But look this guy over and maybe even ask him a few questions to see if you get comfy with him, before you buy.
