Nick, I have a trick I use to find the right seal when more than one like ones come in a package. Get a piece of styrofoam and use toothpicks or short pieces of wire to form a support around the INSIDE of the old seal without stretching it. Then see what new seal best fits over on top of the old seal.

Great tip, skutahuniai! Thank you for sharing. I will try it on the next one an perhaps do a video demonstration so others can see how it's done.

As clean and neat as you seem to be I’m surprised you don’t take the lube dam off the dual planetary and clean it ,it gets a lot of metals caked in between that plate. It’s kinda tuff getting off the first time. But its like anything else you’ll figure out the best way I drive a narrow chisel under it from the shaft towards the outside or finish it up with a screwdriver to the outside that will drive the lip out enough to then come around the outside edge and start getting it off.Also when sizing the rings you don’t need to stretch them slide you a plastic bag over the splines or anything thin plastic lube it and it will slide right over it and then you don’t have to mess with trying to compress them back with the sizer as much. Keep up the good work

I soaked that planet in fresh Dex 6 overnight prior to installing it and it was definitely a bit dirty but should be fine. Yes, they can be tricky to remove and normally I do so if there was a major failure / clutch burnt inside the unit but that 6L80 was basically perfect other than dirty fluid, which is normal for those units. I'll try the plastic bag trick one of these days...Thank you for watching!

I always replace the 1234 balance piston. I've seen that crack and break where the snap ring goes way more times than I've seen the 1234 Piston crack.

[@nickstransmissions]

Yes, it's good idea to replace all the moulded balance pistons and apply pistons in the unit during overhaul. Thanks for watching, Dave!

Are there any books out there for common turbo 400 rebuilds and how I can add/replace a few performance parts to hold higher power like 7-750 range tops? I’m scared to open up the transmission as a novice. Thanks

Hi Tim, can you post the above question in one of my TH400 videos? Once I see it, I'll respond there and remove this one. TIA!
