which trans?
 

Which transmission would be the most reliable? 700r4, th350, or th400? I have 4.56 gears outback and will be between 600-1000hp and will see some street miles, thanks in advance.

don't you still have a 700r4 in your shed? what if you got that rebuilt?
also, update your cardomain! hah

Ya thats the original trans from the car but ive hear bad things about 700r4's and high hp track cars.

ohh ok hah. go on aim!

TH400.

The OD of the 700-R4 would be nice but (from what I've heard) they are difficult to build to those HP levels properly and the 1-2 shift is not very desirable for a track car.

The old TH400 is the way to go. You could find them in the old 427-454 solid lifter BBC and they were bullet proof then. There are a lot of kits that can really make these trans stand up to a lot of HP!

at the race track all the pro teams use a powerglide and they are hands down the best for any combo up to 850 HP in a stock case -- a stock case with an ultra bell and roller mods inside 1200 HP --- and an aftermarket case will all the beans 2500HP have seen top sporstman cars in the High 5s low 6s use a glide as well and some of the top alky dragsters have them as well -- jz

If some street means very little, a PG or TH400. If you need OD a 4L80E or TH400 & GV OD.

200-4R is a possibility as well, correct?

Yes. Well before a 700r4/4l60e. IMO

Yea, thats another way to go.



TH400 and 'glide are others, but its whatever fits your setup correctly. A glide is only a 2-speed so keep that in mind.

I would look into getting a 200-4r built up....they ride behind single digit turbo buicks all the time, so a light 3rd gen shouldn't be too much of an issue.

Bah - sign up for FQuick instead!

before I picked up my T56, I was gonna run a beefed up 200-4R. same gear ratio's in 1st-3rd as a TH350, and has a deeper overdrive than a 700-R4. plus the hydraulics in the trans itself are routed better.
