Transmission problem
1969 Ford Truck V8 Two Wheel Drive Automatic? Miles

c6 transmission, 360 v8 9" differential. Unsure of the mileage, but runs like a champ. Seattle to orlando, to jersey, to orlando, back to jersey, zero problems. New house here has rediculously sloped driveway. 1k lbs of crap in the bed and another 2k in a uhaul trailer. Backed it in reverse up this driveway and had to manuever along side the house, took 20 minutes. Truck was going nowhere, and made this hopping feeling. Now after the incident at 50mph if I cruise or let off gas it feels like driving over the wakeup strips on a highway, rumbles and shakes the whole truck. Under hard accel its fine. At 800 rpms idle in drive let off brake and she rolls on her own just fine. Shifts fine too. Around town shes fine, just on the highway 50mph and above when cruising or deccel, god aweful noise and vibration. Thanks guys.

If the level/filter and condition of the fluid are okay -you have an internal tranny problem to find out get it pressure tested this is the best I can do for you-could be valve body/converter/governor/clutch and band who knows

Its not suppose to look like that-check the transmisiion cooler could be leaking internally to include the radiator

The transmission fluid is not supposed to be pink? Thats the color it is when you pour it out of the jug from the store.I dont have a transmission cooler. The reason I was told for it to go through the bottom of the rad is to help it warm up.

I apologize. I understand the internet cant possibly be a magic pill to auto repair, but a helpful tool. You must be thinking red, with pink being waterlogged. I meant bright pink and normal. This problem was a coincidence and the driveline ended up needing new ujoints and carrier bearing. The transmission has ran fine ever since.
