A833 Installation Opinion

Get yourself four pieces of redi rod that screw into the back of the bell housing about 6'' long.
Side the transmission over the redi rods installed.
This takes the weight off of the front of the transmission while you wiggle it in place from the back.
Have the transmission in gear and turn the back of the output shaft while you wiggle it.
DO NOT try to suck it in with the 4 transmission bolts. It should go in fairly easily by wiggling it and pushing on the back.
You must have the clutch aligned with a proper alignment tool first and the pressure plate torqued to specs or it won't go in.
Won't go in and you didn't have an alignment tool?
Well the quick and dirty way is to do what i said before and have someone push on the clutch slightly so it will move around until you get the trans in and fully seated on the bell housing.
Install the rear transmission mount and slide in bolts and tighten finger tight.
Remove the redi rods and install the transmission bolts one at a time starting with the top ones.
Then tighten all bolts to specs.
Install shifter and rods.
Adjust clutch free play.
