rick_d said:it's a nightmare to stick a 1983 3B input into a 1989 2H transmission.
Tapage said:why .. ?
I thought aren't the same H55F for my 2H and for HZ engines .. diferent input shaft again I thought ..
rick_d said:uh urgent correction.
the later, often using a sealed orange (or black aftermarket) input bearing. the input shafts DO NOT INTERCHANGE, nor do the bearings.
pull the figure 8 bearing retainer (front of transmission) and look at the bearings side by side.

Correct , My old 2h shaft on the left with the coarse spline,and a new 1HZ shaft on the right with fine spline also its a bit longer.
It is my understanding that the later Toyota stock gears are identified by a v shaped nick in them and that they should not be used in an early model box.rick_d said:no, bearing alone won't make them work.
late transmissions will take HZ input shaft, early transmission cannot
(without machine work and then still a ???)
october 1985 is cut off date.
digging up an old thread here, (and highjacking!!)
EDIT: looking at bellhousing combos, i assume i would use the h55f, 3F? bellhousing and the 1F engine (if the bellhousing will bolt to the 1F)
