TRNW-2: 8HP75 are these rebuildable

[Healy Powertrain]

Thats like saying no to a 700/4L60 in 1989...

I believe its considered a non-serviceable unit by the OE, but its just like any other supposed to be "non-serviceabel" units that turned out to be very serviceable.
Complete Gear Train is held by small clip behind rear seal.
There is a seal thats difficult (riveted) to replace (D-Clutch). It has to be drilled and re-centered. Transtec has a tool available, but you can make your own. Same clutch needs a Thicker Pressure Plate, so does Clutch A with the earlier units (Pre-2019). Those are available from Sonnax
D-Clutch Shell Is always worn, check other alu hubs for same wear.
Some Pre-2015/16 (not sure) need an updated Planet #3> Pinion washers changed from plastic to copper.
Valvebody is similar to a 6HP. Check for same wear patterns.
Unfortunately TCM is not available seperately.

Its odd that most parts places have not much available other than the basic OH/Seal, Friction/Steel kits.
Eriksson Industries has more parts, or can at least get the correct parts.
Have Fun!
