I,m doing a new motor and supercharger this winter and should see about 8/900 rwhp. My 4l60 is already at the end of it,s life. I,ve already have a really nice turbo 400 just having 2nd thoughts. I only drive to shows and the dragstrip a few times a year.

Can't seen it being that bad if you only drive it a handfull of times a year....only thing that's gana suck is no down shifting unless your pretty much at a stop...and throwing it back into first every time you stop..

its not bad i drive mines when the weather is good and as far as the shifting goes....i just shift it normally if i need a lower gear i just shift it without stopping and my builder said it wont hurt a thing

I believe a TH400 can be built to handle the same power with a forward manual/auto VB. Is there a reason you want a reverse pattern or is that just what you have?

My TH400 that I built myself works fine with 850hp. I like the fact that it shifts itself.

I,m sure I,ll get used to it, especially since it,s not a dd. I bought it with the rmvb, the forward manual vb sounds pretty nice. What gears are you guys running?

You'll be fine. Shifting isn't an annoyance either.

my buddies got one in his z06 w/3.42's and it'a not that bad on the road, twin turbo car so he can just leave it in 3rd all the time though

I figured I would hate it too, seeing as how I have always been a six speed guy, but honestly I like it. No more clutch or hydraulic woes and you still get the fun of shifting gears, just without a clutch.

I have a Jake's th400 and a pro-ratchet so I think its pretty fun to drive. I'm ready to see how much difference the new engine and power adder will make with the th400 though.

Previously, I had 4.10s and 28" drag radials on my car and it was okay. I think 60mph was somewhere around 3,200 ish. Now with all of the new stuff and the single front mount I think I am going to go around the 3.27 or 3.55 range, still using the 28" tires of course.

Good luck, hope this helps.

what are some dues and don'ts with a manual valve body transmission..? fixing to seal the deal on a recently stock rebuilt th350 with shifter/lines/cooler the whole set-up and it has a TCI rmvb....I rode in the vehicle it's coming out of, shifted nice...anyways first time with the manual valve body..what are some tips...? like maybe take it easy on the down shifts...?

No downshifts. Always start your burnouts in 2nd gear and click into 3rd in the water box. And make sure you use a temp gauge with a sensor jn the pan and always keep an eye on it.

NEVER let off the throttle at high RPM in 2nd gear. That is if you like your feet and legs.

So, at the dragstrip, the car gets squirrley at the top of 2nd gear. So you say if you lift (like you should) the transmission will explode?

Interesting.

Yep definately helps, I picked a new converter today, now I have to get a driveshaft and change the rear gear.

Thanks guys

If you need to lift in 2nd gear, lift and then click the car into high gear as soon as possible and allow the car to decel in high gear. If you let the car run down in 2nd gear, the direct drum can overspeed to 2x engine rpm and a stock cast drum can burst.

love my rmvb th400. Just be careful if you don't have a badass sprag in it you'll roll it if you spin hard on the 1/2 shift. If you roll the sprag you'll lose 2nd gear

Even a billet drum can come apart. A SFI trans shield or blanket is highly recommended in any manual valve body TH400 setup. Street or strip.
