Ok.. my second post of the night. This isnt exactly Mustang related, but this forum is extremely knowledgable and I havent found any F-150 forums that are all that helpful.
Let me do my best to explain this. I noticed it tonight while checking on a strange sound I keep hearing in my truck.
My truck has had a kind of "thud" for a while now. Its only present when taking off from a dead stop. If you've ever heard the sound anF-150 makes when the bed bolts get a little loose, thats about what it sounds like. Kinda a metallic klink but a little deeper. Anyway, while trying to source the sound tonight I had a friend looking under the truck while I would power-brake then let off. Whenever I let off from power braking I also get the sound.. and since we couldnt figure out a way to safely see under the truck when I accelerate, this seemed to fit the bill.
So, the sound is coming from the transmission, seems to be centered in the bellhousing. When I power-brake and release I get a kinda knock, the idle drops drastically and a little transmission fluid spurts out of the bellhousing. Not good. Once it even made an almost grinding sound for a second and the truck died, heh.
The truck is also sluggish from a dead stop. Its reluctant to take off worth a damn. Once I'm up to 15 or so MPH it picks up will lay you back.. but dead stop acceleration will cause a couple knocking sounds and its feels like the truck is gutless.
The truck drives extremely well in other circumstances. Cruises fine, transmission shifts pretty well, accelerates very strongly once I get going. First gear itself doesnt seem to be the problem, since its fine once I get past the initial 10-15mph.
Could this be a T/C issue or something else in the transmission?
Any info would be very helpful.
The transmission is a 4r70w in my '94 F-150. Approx. 115k on the T/C and the transmission was rebuilt about 25k or so back.
