700r4 ATF

[yevgenievich]

Generally, old 700r4 with original style clutches will work fine with regular fluid.When it is rebuilt with upgraded clutches/steels that it can benefit from synth fluid

Cheap ass Dextron IV/Mercon from Walmart is fine. About $11 a gallon. Change it every 50,000 miles and you'll be good to go. I'd say 75,000 but if you're doing any towing or lots of city driving, heating conditions and it being a 700r4, then just better safe than sorry so do 50,000 miles and you should be able to sleep at night.

If it were a Th350 or Th400, I'd say every 75,000 - 100,000 miles. I've seen them get close to 200,000 and more without ever being changed.

I've run SuperTech from Walmart for 5+ years in both 700R4 and TH350s. No problems.

Same here. I've used this fluid for my 700s in the past and currently. Works great and is cheap on the wallet.

That's why I use Super Tech. Buy it by the gallon and it's cheap. I was $9.XX a gallon a year and a half ago, I just bought a gallon and it's now $12.XX a gallon. Still alot cheaper than $3.89 a quart if you can find it for that.
