Hey all,
My name is Brad and I am brand new to your group. I have a question maybe someone can help me with....Ive got a 91 f-250 2wd 7.3 with the zf 5spd(single mass flywheel).My problem is that My trans is making a growling noise when in neutral and I cannot figure out what it is. I took the transmission out and tore into it and I did find one of the roll pins that hold the shift fork to the shaft in the bottom of the case. NOt sure if this is causing the noise or not, The shift rail that the pin came out of has 2 holding it on and it doesnt appear to be slopppy or anything, I just cant help but wonder why that pin came out....Nothing in the transmission looks to be damaged....no unusual wear or play in the bearings. The gears and sycros appear to be in good shape(but I do have very limited expeirance with the manual transmission Internals...But from what I have read in books and seen in other transmissions everything looks great. So does anyone have any Ideas as to what the problem may be? The growl seems to be loud underneith the truck when it is running, But like I said I have limited expeiriance with these so I am hoping someone else may have encounterd the same problem. (OH yeah,....The truck was bought used and had 80w90 gear lube in it when i changed it....Could that have destroyed somthing? Thanks, I look forward to your suggestions.
