I thought I’d share some more tech info from our daily work here at the shop.
Earlier this week I started building another transmission and Tcase combo for a long time friend; @wngrog
The requirements for this combo going into an FJ40 build:
1981-1984 short 19-spline output H42
New OEM split case
40-series cast iron top cover
FJ60 transmission shifter
Early FJ60 Tcase shift linkage
Early pattern split case flanges, no e-braje
We started with a really good 1982 H42 core we had in inventory along with the rebuild kit and new synchro rings.
We completed the full rebuild utilizing the case and gear set. These cases have the Tcase linkage boss/threaded hole in the proper position for the early factory linkage, they also have the 4 threaded holes for a transmission mount. You could use the earlier 1975-1980 case as well but they don’t have the mount provision.
Next step was to make the late model split case work. This requires 3 fairly simple mods:
1) You can only run one alignment dowel.
2) You have to plug the factory hole below the input seal.
3) You have to clearance the front case half slightly at the forward facing side to clear the transmission countershaft bearing.
Here’s a pic of the freshly rebuilt H42 trans with one of our Sumo Gear Co full-spline input gears.
