- 727 will bolt right up.
- PCM won't see it, so you'll have to get it flashed out, SCT can do it but the dashboard indicator will be a light show till you cover it up.
- You will have to notch the bell housing for the crank sensor. John Cope did it fo me.
- 46RE converter won't work, it'll have to be a 727 converter.
- Custom transmount...It needs to be about two inches longer, (tranny is shorter) I can get a pic of a modded one and stock one.
- Driveshaft will have to be longer/custom.
- Flex plate...I had to open up the holes a little on my flex plate for the bolts to fit.
- I think the tailshaft of the 727 is thinner than a 46RE, I swear my engine is angled down towards the back more than it was. If your engine is still in the truck, jack the front or back of the truck up till the bedrails are dead nuts level, put an angle gauge on your crank pulley and record the angle...After the swap, level out the truck and check the angle and adjust it if needed with shims between trans mount and tailshaft.
- Check Pinion Angle after the swap.
- Enjoy...
