h150/151 early vs late spline

[rick_d]

In 1999 models the input shaft of the transfer case switched from a shaft with pressed on gears to an all in one gear and shaft. Are the splines on the transmission the same?

 

[mudgudgeon]

are you asking about the splines on transmission output shaft?

 

[rick_d]

yup.

Really want to know if all the transfer cases can fit on all the transmissions. I have the early spline system and can easily test. But I do not have one of the gear/shaft combos.

I might be ordering a new case from overseas, the late are 48kg the early are 62-64kg.

transfer cases from HZJ105 are definitely not compatible despite having the same designation, I believe all 80series transfer cases would be, but there is differences with VC, full time/part time etc

I am ordering a JDM 2015 GRJ transfer case to fit on my 1991 transmission. I'll tell you how it goes.

Early transmissions H151/150 use 60120 main shaft which in turn uses 60030 (or 60040) transfer input. Transfer input shaft for HDJ79 (2006) is a 60040 input. Main shaft in hdj79 H150 is 60140. Main shaft in a JDM 2015 GRJ76 is 60140. T case uses all in one gear/shaft 60120 for grj. Ass end of all transmissions begins with 60070- then 60071 and 60072 BUT the 1999+ models use 60170 housing (non separated seat).

I have a 60170 ass end on my 1991 transmission (and a 60161 front end to get the 70 series tcase mount)

I seriously doubt they ARE NOT interchangeable.

just an update.
-60351 2001-2006 hdj79 tcase fits a 1990-1992 hdj81 transmission with zero issues. Shipping was 50% cheaper for this one from UAE over the grj76/9 out of japan.
