ZF6 3rd gear issue, PLEASE HELP!
Hey guys, just picked up a 2003 f250 7.3 zf6, works great got it for a good price due to some hopefully small issues.
First off, the truck had a dp tuner, straight pipe, volant CAI and an upgraded clutch (previous owner did not know brand)
My problem is, that my transmission will not go into third gear every time (although about 25% of attempts work fine, and while your in third there is no problem)
The feeling i get when i put it in third most of the time is almost like the gear isint even there, like its in neutral.
Have tried shifting with the clutch and without it, no difference.
Need some input, im stumped!
