Re: 700R-4 Overdrive Downshifting
I have a 91 burban with the 6.2 banks sidewinder turbo diesel. Just got it about a month ago and have put about 600-700 miles on it. Running 1 1/4 axles with 4.56 gears and 37" tires, but mine downshifts from O/D to 3rd constantly when I am running 55 or higher on the highway. PO says the 700R4 was rebuilt about 6K miles ago. I have read on numerous forums now, that downshifting is common with the 6.2/700R4 setup. Hasn't bothered me too much, however I guess I am not towing like you are...
