1986 f250 6.9 diesel engine bogging down
Well I had the transmission rebuilt not two long ago. and the fluid was red but it did smell burnt and there was this thick grey sludge in the pan. I did do a filter and fluid change but did not get the right amount of fluid so I have not road tested it yet
Had a shifting issue on my bronco with a c6 it had was right after a rebuild a did, turned out to be the modulator valve on the back, replaced it and was smooth sailing till I parked it into my garage, that was 2 years ago, It is now awaiting the transformation into a dirt toy, going to drop a powerstroke into her and redo everything I just did LOL , may get another bronco to restore real nice and the the driveline into her. 

On your rear diff, is the cover on the back side or is it facing the front of the vehicle?

I would go to the auto parts store and pick up a modulator for your transmission, and depending on where you live will tell us which one you need, Since I live in the Valley of Arizona I would buy the green striped modulator since I don't need a altitude compensation. Will run about $30 for the part.
