5spd, worn synchro
Hey all, I have a 5 spd in my 03 f150. 2nd gear synchro must be worn, when the tranny is cold it shifts good but once it warms up it will grind when shifting into 2nd gear. All others are good. Only 2nd. I'm assuming there is a little of the synchro left as it works ok cold but basically its about toast I think. I was posting here to see if anyone had a suggestion for any additive that may help a synchro issue? The truck only has 80,000 miles on it but the PO ran it in town mostly, and I assume he wasn't very good with a manual shift, thus the messed up trans.. I know the real fix, pull the tranny and get it fixed. Was hoping for an improvement in a can, otherwise it will just stay this way. I've already swapped engines. I'm not interested in the tranny too!
Thanks for any advise!
