Man I want to buy the "Master shift recalibration and assembly upgrade kit" from CK Performance, but they absolutely will not answer the phone nor call me back. I'm a little reluctant to give my money to someone who won't talk to me on the phone. The main thing I wanted to ask them was if that kit has the parts to rollerize this 4L80..... Looks like I see the TH350 pump bearing and shims top right corner, but it would be nice to confirm....
I guess I need to start thinking about a different shift kit for this..... Obviously the HD2 kit is useless since I'm already inside the gearbox and have done the dual feed internally.

So cline you must think that CK Performance is OK to do business with? It is a little concerning that they won't answer the phone but I'm sure they are busy and get tired of answering dumbass questions so it's understandable I suppose.
Also, I have several checkballs from a grenaded 4L60, looks like I can jam one in the reverse feed of the center support. Are they the same size as the TV exhaust checkball from a 700R4? And what about just welding that hole shut?
I noticed that the forward clutch piston looks very similar to the direct clutch piston. Is there any reason to upgrade that one since the direct clutch gets upgraded to a TH400 style in the shift kit CK performace sells???
Game ova, did you ever get a hold of them lol?
rpturbo, yeah I was thinking maybe we could do a compilation of 4L80 how to here? I can take pics and come up with captions as I build mine up over here. And, we have cline offer his insight, which is a great resource.
cline, thank you for sharing your knowledge and experience with all of us. We are very fortunate to have you man!!!
Where do you guys think I should mount my trans temp sensor? I was thinking just in the pan somewhere.

The 700R4 TV Exhaust checkball is about .015" larger than a standard 1/4" checkball.
The 4L80E Forward & Direct piston are different than each other......But you can run a TH400 piston in the froward drum, But the center sealing ring will no longer be effective, So you might as well remove it!
Because of the different heights of TH400 pistons.......You have to make SURE that the Wave/Cushion plate CANNOT slip under the relief cut it the drum!!!!
The Forward Clutch is static in every forward gear. The TH400 piston upgrade is not needed.

Well I have left 3 or 4 messages with CK and none of them get returned. Just left the last one 5 minutes ago.
Aaaaannnndddd..... Their website is fucked up and not letting me checkout with the Master recalibration kit......
So...... Who else makes something comparable to the master recalibration kit they sell. I'm pretty much done with CK. If I have to chase them around to try to give them my money that's pretty gay in my opinion.

Well later that night, I was able to push an order through on their website. The parts should be here tomorrow.
I'm looking forward to getting them so I can continue on with this 4L80 buildup.

Still slowly building this 4L80! I got the Ford AXOD rear sun gear thrust to rollerize the forward drum. I searched the part number, found an Ebay listing where it was advertised as such. But alas! It doesn't fit! And it looks like Green Sales doesn't carry the correct bearing anymore either! So I guess I won't be rollerizing the forward drum.
To you guys who have rollerized the output.....
When I was measuring the rear unit endplay I found that just the torrington bearing by itself got it within spec.. Adding shims to that would have pushed the measurements outside of spec.... Anybody else seen this happen?

Yes that's fairly common. I usually measure the endplay before I take it apart, then measure the stock thrust washer and selective tang washer. Then I can select shims to set proper endplay. Sometimes you don't need one.

Thanks for the confirmation Maroon! I felt comfortable with it but figured I'd draw on the community for alternative information and opinions if I could. Appreciate the feedback. I guess everyone else that was in here left lol!
I'm having trouble sourcing the Ford AXOD thrust bearing like I mentioned above so I'm going to go ahead and build this 4L80 without rollerizing the forward drum I guess. Wish I could find that thrust bearing but if it's this much hassle I'm not gonna mess with it.

Cline, do you have any info on rollerizing the forward in this manner? I've heard and read about it but never seen any solid resource. I've just always used a machined forward hub. Can it be rollerized without machining?
