3 speed manual to T-400 conversion trans yoke?
I have put a T-400 auto trans in place of the 3 speed manual and everything is bolted in but the drive shaft. It is measured, shortened and balanced ready for install. I will need a cross-over u-joint until i can swap the yoke. Does anyone know the part number or ID on this u-joint?

Re: 3 speed manual to T-400 conversion trans yoke?
If it doesn't have the tranny yoke on it, it isn't balanced..
You need to figure out what kind of ujoint the tranny yoke is and what kind of ujoint the driveshaft is (probably 1310) should have had the driveshaft shop put the right weld yoke in the driveshaft that matches the tranny yoke.

If you change transmission yokes you change the balance of the divshaft even if you use a conversion joint... or even if you use the original joint. If you're able to measure the ujoint I can give you part numbers or even sell you one. But even if your but dyno doesn't feel a vibration that doesn't mean that you aren't risking damage to the transmission. Its best just to do it right the first time.
