Need opinion...700R4 or T-400

I have a 1987 V10, 4" lift, 33", NP208, tires, i use this truck for everything, daily driver, towing, hunting, EVERYTHING. I am on my second 700R4 and its about to go out as well. I need so honest opinions and why, but i cannot decide if i want to rebuild my 700R4 again but with a Monster transmission rebuild kit, or go with a TH400. Some people even said to put in the 350 turbo...but i don't know everybody has a different opinion. What is yalls take on it...
thanks a bunch.

IMO, build the 700 stout...you need all the gas mileage help you can get

Do you own a refinery?

Ok then the 400 will be strongest but a th350 can be built strong... probably either would work just fine

what trans

Don't waste your time on a 3 spd when you already have a 4spd. Just get it built right and stay with the 4spd. Has a better 1st gear too.

The th700r4 is an inharently weak transmission in any high performance application.
You will spend more on rebuilds than save on gas.

its good for low power low rpm cruisers.

700r4

Ya it is a weaker trans than a T400 but tell Monster trans that or B/M or TCI a whole different story if you buy a properly built trans, like saying a 10 bolt is no good, sure compared to a 12 Bolt, all depends on the use of it. Drive hard then pay for quality parts or it won't last.

It can be built to handle some abuse. I'd check with a Builder who specializes in the 700R4/4L60 over Monster.
Dana >> 700R4 & 4L60E Automatic transmissions specialists - ProBuilt can put a strong package together for you.

you are on your 3rd... you are either hard on the trans or the builder sucks.. sorry for being blunt..
you didn't list what type miles you got out of each rebuild.. ??

I'd maybe step up to a 4l80e.. basicly a th400 with a o/d
or install a th400 if your milage per gallon isn't that big of a deal..
might try not use'n o/d when tow/pull/loaded up.. o/d is the weak point in those..
I'm asumming (dangerous I know) that you have a cooler.. and the trans death is from other things than lack of servicing..

good luck... many trucks with tons of miles on those 7004r's..
but upkeep and t.v. cable adjustment have to be correct and followed..

maybe go to the 4l60e and get the v.t. cable gone..
