Tranny build outcome and carnage report..

The install/build was done a couple weeks ago and everything seems to be working great. Before the tear down, the truck seemed to be working fine, just that I had a lot of slipping on the lockup clutch when rolling into the throttle and the usual loose converter while cruising around. When I pulled the transmission apart things where ugly and not expected, the clutch packs where fused together and I had to put everything on the press and force them apart. The directs where toast, completely metal and so hot that two of them looked more like wave washers then fabric plates. The teeth of the disc ate into the splines on the input gear; somewhat rotated/stripped and ruined it (ready for replacement anyway)...


The tranny now has the following:
-DPC triple disc converter
-Billet Input
-7 disc Red Alto direct pack
-5 disc Red Alto front pack
-Kevlar flex band
-Billet anchor and strut
-4.2 billet lever
-Sonax apply piston and servo
-TransGo kit with pressure screw turned up 2 turns (pressure 75-160)
-GM governor conversion (fixed my early shifting problem)
(transgo was installed to instructions with only 1 hole drilled for lock up, the band was adjusted to factory specs but might tweak it a tiny bit 1/8 turn tighter)...

and
-HD SFI flexplate

WOW, when everyone says a tranny/ converter upgrade is worth it, they are not joking... The overhead lie-o-meter says a 1.5mpg gain, I haven't checked it by hand, but I can definitely tell a improvement (or lack of movement) with the fuel gauge...


Truck runs like it's 2500lbs lighter, shifts exactly when it should, nice a firm but not tire chirping, and lock up is nice and firm... Cruising, and hill climbing is now effortless instead of listening to a flaring up engine that wasn't putting the power to the ground it just holds rpm and chugs along. Now it seems like the tranny laughs at what ever the engine can dish out (stock 305/555 with Smarty SO6 and MP-8), before it would squeal at the slightest throttle and converter would slip the lock up clutch like crazy...

Once again I actually get excited about driving the truck just like I use to when I first got it... I can't wait to hook the trailer up and try it out when towing the jeep...

Thanks everyone for the build advice and thanks Phil at DPC for talking me into a triple disc instead of a single... No regrets, I hope this tranny last me for a long time...

Awesome!!

I bet it feels like driving a whole new truck again. I know when I did the clutch on mine a few months ago it was night and day difference when I pushed the go pedal

Had mine done about 50,000 miles ago. It works like it should have when it was new.
