I just bought a 01 HO that the previous owner was running Amsoil in the transmission and diffs... . the trans mission shifts pretty well when it has been driven for an hour or so but if you start up cold and drive across town it will grind in every gear especially 4th it goes through the synchro but the gears are not spiining the same speed after it goes through the synchro so it will either grind or you will feel a little bump bump as it goes the rest of the way into gear... any help with this would really be appreciated...
Thanx Lowell
