Rebuilt 700r4 Burnt in 10 miles

Just finished installing a 700r4 in my 69 truck and tested everything with a pressure gauge and ensured the tv system is working correctly and then took it to the shop that built it to check it out and they test drove it and said all was fine. Then I left there and drove back, and now I have only first and reverse, and my fluid is burnt. The tranny shop is going to pick up the truck and diagnose the problem, and fix it for free, but I want to know what caused a newly rebuilt tranny to die in 10 miles of driving? I am running trick shift fluid, and instead of the pretty blue color, its blackish. The tranny is toast. I am just very frustrated as it drove perfectly prior to being turned off, and now it is dead just like that.

From my very limited exp. with transmissions, I dont know if the 700-4R suffers from the same problem the 200-4R suffers from, but a not perfectly adjusted TV cable could kill it with-in a few miles. I would'nt use that aftermarket tranny fluid either.

I have a few questions, Did you install a aftermarket tranny cooler or run the one in the radiator? is the lock up function in the converter being used or not?

Can't say for sure, yoru tranny shop will find it. However, unless they installed some part backward, the main cause of premature failure of these ODs is mis-adjusted TV valve. What carb/TV cable adjuster are you using?

The tranny shop did something wrong. Its harder than you think to miss adjust the TV cable that much in order to burn the tranny up. I had a 200 4r in my car and it burnt out as fast as your did twice on me. The shop I had do it wouldnt rebuild it either time and said I mis adjusted the TV cable. I had another tranny shop look at and they pointed out 3 differnet problems with the tranny when they took it apart and reinspected it. After all this I just had a "built" 700r4 made for me and said nuts to the 200 4r since I couldnt find anyone around here to make a "built" 200 4r for me. Installed the 700 r4 and have looked back since.

I had the tranny shop that built it inspect the TV cable set up and adjustment and they said all was ok. 10 min prior to it failing and burning up the fluid. I am running a Hayden cooler that is 15 by 10 by 1, and not the in radiator cooler as I have no idea what kind of garbage could be in it. The lockup function is being used, and I am running a TV kit from 700r4.com(bow tie overdrives) for my Holley Carb. Is there some problem with B&M Trick shift fluid? From what I have read it is supposed to be better than stock fluid.

From what I understand the B&M fluid is essentially Type F. There is some sort of friction additive that supposedly gives you firmer shifts and whatnot. I dont know if there is any longevity benefit from having it in your tranny.

I could be wrong tho lol.

You are correct, TrickShift is essentially Type F fluid that is dyed blue, plus some magic elixirs. Should be at least as good as normal type F so I highly doubt the fluid is the problem.

Cool

trickshift fluid has been around since dirt was invented.....

I doubt the fluid was a problem.

I am interested on what caused the tranny to die
