Hi names joe I'm from el paso, tx 22 years young. Well I purchased a 1981 f100 from some guy and well when I drive it shifts perfectly fine the 4 speed OD tranny doesn't slip or anything but it does make a clicking noise that seems to get louder and fast as I accelerate but only in 1st and 2nd gear not in 3rd or the OD. I just recently got the tranny fluid changed thinking that was the problem but it didn't work sadly. Anyone have any ideas?
Expecting the worse I've been looking for a new AOD tranny to put in the truck and I found some guy selling one for $375 but its a 4x4 so I don't know if it will fit in my truck so any possible advice if it would or wouldn't work?

 

If your truck is 2wd, then a 4wd trans will not work.

As for the clicking sound, check the u-joints.

 

Would the u-joints be the cause of it only being heard in firsdt and second gear? Thank you for your reply!

 

What about a aod transmission from a 89 mustand 2.3l

 

Again, no. Won't bolt up to the motor.

Have you checked the u-joints? They are prone to clicking/squeaking at low speed, that seems to go away by about 30-40 MPH. At only $10-15 each, they're a cheap fix.

 

I agree with the u-joints. The other possiblity is the speedometer cable. Does the speedo jump around at low speeds then smooth out above 40...lube the cable with white lithium grease in a can.

I would say the tranny is fine.

Speedo cable. U joints. flat spot on a tire. not likely the transmission.

memories come flooding back. We used to put stainless steel zip ties around a buddies driveshaft on his dodge cause he could never figure out what was making the noise. I don't know how he never noticed it.

 

Took it to a mechanic and he said it was coming from the front of the tyranny so I'm waiting for the results.

 

Personnally if your not 100% sure what the issue is I would just drive it till you have some real problems like dropping a gear or something. Also there are plenty of trans out there in Crown Vics and stuff like that that had a AOD that came from behind a 5.0

 

Not sure if its aod its a 4 speed with the 4th od with a 300
