5-speed OD manual trans to 390 FE possible?
The 4-speed manual trans in my pu is jumping out of third gear,and it's getting to be time to replace or update it. It is a 1971 Ford F-250 4X4 with a 390 FE engine. What do I need to put a more modern 5-speed manual overdrive transmission in my truck? Is it ever possible?

To my knowledge...it is NOT possible to install a ZF (FORD) 5 spd to your FE engine. The bellhousing is part of the tranny case...and cannot be modified.
However...there are kits available to install a NP4500 (Dodge version) 5 spd tranny on the FE engine. This is a very popular upgrade!
Do a search in the FE forum here at FTE...and I am sure you will find it. I would give you the FTE member who did the conversion...but I cannot remember. Sorry...

check out advance adapters they have a two speed spliter that goes infront of your trans and is od/1:1 or underdrive/1:1 so that would be like having a duplex trans like an old mack truck except it will shift easy and at speed without skill!
