Tranny oil tends to burn when the Tranny is going and when people rev their engines to move the vehicle. In my experience, when the Tranny oil is burned, it tends to lubricate the burnt interiors on the trany better than new oil.

If the oil is burnt then that should be a sign that ur tranny has been overheated. If that happens, you belts start to slip.

Be careful when you rev ur engine to higher RPM's. You dont want to blow a head gasket.

Again, this is just from my experience of going through four FORD transmissions.

Good luck

 

Ok, I changed the fluid and filter. I half expected to find a bunch of "gunk" (my technical term) in the bottom of the pan. But it was relatively clean. Fluid was dark but it did not have a burnt smell to it.

After I filled it up and gave it time to warm up, I went through the gears. Reverse is not a problem but it is still having problems going into Drive. With the brake on, it took it 2 mins before it acted like it wanted to shift into drive. If I let the brake off and tap the accelerator (RPM's 3000 tops), it goes into gear.

From 89Bronco_EddieBauer:

"When you shift from park to drive or drive to reverse, do you hear a "slipping" sound. Does it shift hard while you drive?"

Not that I can tell. The truck is kinda loud due to the exhaust setup. Once it is in gear, it shift pretty good in my opinion. How due I check the bands/belts?



Anyone have any other ideas?
