trans upgrade
it looks like we are going to have to wait to upgrade to a newer MH so I would like to upgrade the Turbo Hydramatic 400 to the 700R trans. Has anyone done this here? Seems at 65 mph its topped out, so...

How hard is it to do the controller for the lock up? I'm fairly good at doing these thing but not getting any younger for sure and I do have friends that would help with the fabrication if needed.ScottG wrote:does the overdrive unit have a automatic controller?
That would be a big job. Mounts would have to be created and something would have to activate the locking torque converter in the 4 speed that you don't have now.
Have you considered getting an overdrive unit like Gear Vendors sells? They would probably have a kit to just bolt it in after shortening the drive shaft.
My FIL had one and it worked automatically just like the forth gear in an auto.
