I ordered the $595 performance master rebuild kit off of EBay (it has quality parts), https://www.ebay.com/itm/A618-A518-4...EZA6:rk:8:pf:0 Sonnax Zip Kit (has the remaining metal servos), Kevlar reverse band, HD Borg Warner pressure sensor and solenoid, overdrive and tcc solenoids, output speed sensor, filter, fluid, torque converter and misc parts he has you replace just because. Ordered these off EBay too. Read the Zip Kit instructions before putting the transmission back together, there are parts that need to go inside (other than the valve body) the transmission while rebuilding. This list work?

 

Pretty good if I do say so myself, other then the misc parts lol

 

On page 6 of MonteC's trans corner, he has a list of suggested parts for another member, that regularly towed a 7000 lb trailer. Going by that would give you a nice, stout, trans as well.

 

I'm going to give that a lookski
