transmission upgrade questions

[cuda hunter]

This is a question that is for a 203 4x4 727 out of a 77 Ramcharger.

Detroit Matt over on febo did this to his 727 and I'm wondering if I can do the same to my 4x4 727 trans.

Please inform me if this will work.     (and if anyone knows of a builder in Colorado) (yeah right)

Here are a few of the improvements made to my trans. I found a used late '90s 46RE on Craigslist as a doner for some of the mods. The valve body got a shift improver kit and the oem steel check balls were replaced with the composite ones from the 46RE as they don't beat up the separator plate like the steel ones.
New TCI HP intermediate sprags.
New style dimpled input bushing in pump housing for improved oiling.
Replaced main output shaft bearing.
Back planetary set was replaced from the oem 3 gear set to the 4 gear from the 46RE.
Front clutch pack springs went from the 9 originals + 3 reds from the 46RE to = 12.
Front clutch pack bushing replaced with new updated grooved style for improved oiling.
Front clutch pack discs changed from 4 oem to 5 Alto-red .062 discs.
Back clutch pack discs changed from 3 oem to 4 alto-red .062 discs.
Kick down apply lever changed from 3.2 oem to 3.8.
New front and rear bands, good ones.
6 1/2" washers used as blocker in the low/reverse apply piston assembly.
Removed casting flashings from case(one was dangerously close to falling off which would have been disasterous)
