Not long ago, I tore out the splines between my stock/OEM input shaft and it's associated clutch drum thingy . . . . It was a good shaft and has served me very well. May it rest in peace.







Further, there was some excessive wear (IMO) of the planetary gear-set thrust washers. At this point, the mess was a mix of 46RH & 48RE ring-gears, thrust washers, etc.





So, I've gone and upgraded the input shaft to the 2-piece billet/300m alloy unit that sports an increased spline count between the shaft and the drum.
I've also upgraded the intermediate shaft to a billet/300m alloy unit.





With that, I've managed to make an almost complete transition to the 48RE rotating assembly [less the front clutch-drum (ref the NON lock-up input shaft), the low-reverse drum, and the output shaft]. All planets are the 6-pinion/steel carrier. The thicker 48RE shell, and 48RE front planet ring-gear & clutch discs (increased spline count).





Daggum thing's heavy!





My transmission now amounts to a hydraulically controlled 48RE in a 46RH case. Increased clutch/steel counts with 2/3rds billet shafts & converter.


Sneaky little bugger aren't I?


It's sitting next to the truck right now. I hope to get it in Sunday.

Impressive. You make it all look and sound so easy (and expensive)

IIRC, that truck makes mid-400's to the tires and cuts a high 1.6 in the 60'. I know low-11 second trucks that can't get off the line like that. I'd say he's definitely putting it to the ground.

I think David should start a business out of rebuilding these transmissons! I'd buy one, I know that much. Especially because I need one, my transmission cooked on me back in February.

Thanks for the kind words folks.

Trans is working as it should. With no changes to the valve-body, there's nothing much to report.

Now to get back to dialing-in the injection timing as I had just completed the injector POP pressure adjustments before the trans let go. I've also now got the M&H IP timing widget and if I can get things like I want, I shouldn't have to use the KSB power switch thing for racing.

I know who's threads I'll be going through if I ever have an auto to overhaul .

You're attention to detail and work otherwise is excellent, David!!
