1981 300 4x4 Which manual trans?
Hey guys! My buddy was just given an 81 F150 4x4 with the 300 inline 6 and a bad shifting 4 speed manual. We are trying to figure out which one it is (T170 SROD??) You have to push down for reverse (down-left-up) and 4th is OD. He has a very hard time shifting into 4th. It seems like it just won't slip into gear and the shifter feels way too loose but only when shifting to 4th. How bad does this sound? What other manuals are an easy swap? Thanks for the help!

If 4th is OD, it's one of the SROD variants.
There is the SROD, pictured here:
Domestic Truck Tranny Guide
They explain the 3 versions.
Weak with poor ratios.
Depending on your axle and tire size, you may be able to swap in a T18 or NP435 and have good results. Those are also listed.
You may have DS issues, or cross member mods.
As far as fixing the one you have, it could be shifter wear that is fixable with a new part or two... If it's the turret or top shifted one, that may require some teardown.
Parts, rebuild kits:

Going to a 5 speed would be great, but gets more complicated....
