If the trans is in good shape, I'd install a TF-2 kit and let 'er rip.

You've already got a good vb.. If the tranny is good, I wouldn't even bother rebuilding it. my .. replace the stock servos and acummulator with billet pieces(Sonnax,Superior or moparts member sales them), put a max wedge governor in, 4.2(or 3.8) band apply lever and a deep pan with the screened filter.

What about a "Blocker tube" for the servo??
Or is that not needed with a manual valvebody?

Thanks guys
How much would you guys say that a kevlar flex band helps? They are like 35 bucks from Mancini's. I was thinking maybe a shift kit, kevlar flex band and a deep pan. If I was gonna spend money upgrading the valve body I would only wanna buy a reverse manual but like I said before I already own a nice forward pattern cheetah shifter. Don't wanna blow alot of money right now as I'm just a lowly college student who's wife ia nice enough to let play just a little lol
NO KEVLAR for the front band , rear band will be ok but NOT the front band ..
Solid band is better than a Flex , a Hi engery Flex is a good band for the front .
As far as blocking the servo , your choice, the servo dampens the rear clutch applying.
I used to block it but took the advice of John K. and no longer do.

I've never blocked a servo.. learned that from an old timer many years ago.... who happens to have invented some of the very things were discussing I won't say who it was and what it was, him and his partner did. Waiting for MCG to talk with him since Hot Rod and Mopar Muscle don't seem interested.

How is solid band better than the flex? Carbon fiber flex band will hold 1000hp with correct line pressure and 4.2 lever. Of course you can use solid but it more expensive.
Only problem what i have seen is 48re transmission that has 5.0 lever, it will stretch the flex band in 100000miles so you need to adjust it more often.
This rebuild doesnt need much magic with this engine. If its on a tight budget, tear it apart and check what you need.
master kit, 3.8lever, good quality front band, proper clearances and Transgo tf2 kit. Sometimes the stiff rear servo spring(comes with the kit) blows the retainer out, use stock spring, will work ok.

I feel the solid front band releases quicker/better than a flex band during the 2-3 shift. No data, just my 2-cents.
It may not be needed in all applications. Like a low-perf daily drive to the grocery store.

Didn't the early strap bands have problems with ripping apart in hp apps? I never broke any but heard the stories....

You've already got a good vb.. If the tranny is good, I wouldn't even bother rebuilding it.
my .. replace the stock servos and acummulator with billet pieces(Sonnax,Superior or moparts member sales them), put a max wedge governor in, 4.2(or 3.8) band apply lever and a deep pan with the screened filter.
Here is a pic of a servo piston I removed from my trans
I have also seen them break at the outer lip.
I'm a machinist by trade & I live at the bottom of the earth so I machined my own billet pistons but you should have them available close by so change it out while you are fitting your deep pan & sleep at night.

Though I do have a billet rear servo in my street car. None of my cars have ever broken a stock servo. Also I've used every type of band be it flex or Kevlar. Kevlar will destroy an aluminum drum. I've found them all to work with steel drums. The stock style Rabestoes tan clutch's work very well also. No need to spend a lot in your case. The valve body is the key. Doug

I worked as a maintenance machinist years ago. Wish I still had access to a mill and lathe. Machined a fixture for holding governors in a lathe and have several different rpm governors made up. My roadrunner(Hemi street car) upshifts at about 6300@WOT when left in drive
