05 F150 5.4 trans issue...help!!
Today my wife went to drive my truck and said it seemed like it didn't want to go anywhere...
I took it for a drive and it is slipping terribly. When I step on the gas, the engine revs but the truck only slightly picks up speed. I read different posts while searching this issue, and some mentioned that the problem might go away when the O/D is disabled. Mine stays the same. I DO have engine braking when downshifting, and I noticed the trans works fine in reverse... (which I'm thinking would rule out a torque converter, right?)
Any ideas?
Thanks,
Greg
BTW, my paperwork for the truck lists the trans as a 4R75E...

It really sounds like low fluid or a problem with the filter. You really have to be careful on how you check the fluid. I have seen very professional mechanics misread it. You need to check it a couple of times with the engine running. Wipe the stick every time. You are looking for the bottom of the lowest dry mark and not the top wet mark. It's darn hard to read sometimes. I have been fooled myself.

Same thing, only worse. For a little bit 1st seemed to be not as bad as 2nd & 3rd, but it too faded to the point I didn't know if I was going to make it back to my driveway. Reverse is still strong. Any other ideas?
I don't know if its worth it to invest in this truck, I have a rear main seal leak, a transfer case leak and a ft pass axle leak. The VCT's are clacking away, it has 139K on it...
