"T" T50 vs "A" T50 Fri, 30 September 2005 18:13 Go to next message
1. "T" series T50 bolt on to "A" series block with "A" type bell housing. (may face problem, see below)

2. input shaft bearing 68mm vs 62mm. To identify them: T50 with 62mm bearing have round nose cone cover; T50 with 68mm bearing have square nose cone cover.
(some "T" T50 came with 62mm input shaft bearing, some with 68mm like the "A" T50. Using T50 with 62mm bearing with "A" bell housing will give oil leak)

3. "A" with 22-spline and "T" with 20-spline/22-spline output shaft.
(i've personally seen a 2T T50 and it got 22spline output shaft)


4. some "T" T50 have shorter shifter position while all "A" T50 have longer shifter position.


Things i'm not sure about:
older "T" series T50 = shorter shifter position = 20spline output shaft = 62mm input shaft bearing = will face OIL LEAK if used with "A" bell housing

Newer "T" series T50 = longer shifter position = 22spline output shaft = 68mm input shaft bearing = "A" series T50 (only different is the bell housing)

anyone can get me clear on this?

is there anyone who used the T50 with shorter shifter position on 4ag? was the output shaft havin 20-spline? any oil leak from bell housing after using it on 4ag with "A" bell housing?

and also, anyone seen any "T" T50 with everything similar to "A" T50 other than the different bell housing?

i havent ever come across a T50 with the rear shifter position AND the bigger bearings and 22-spline output shaft...

I used the T18 g'box on my AE71... being from behind a 3T-C it was rear shifter position, 20-spline output shaft and the smaller input shaft beaing. I chucked the 4a bellhousing on no worries.....

BUT!!!

i used a combination of the washers in the bellhousing to seal it good, and used a crapload of silastic Smile

The TA12, TA22, TA23, TE27, TE37, TE30, TE51, TE55, TE61, TE65 etc had the shorter more forward shifter position. (more direct, need to pull up for reverse)

TE71, TE72, AE71, AE85, AE86, AA60 etc had the longer more rearward shift position.

I think all of them have a 21t spline input shaft. TA22/TE72 have a 20t output shaft.

Yes the TE72 is the same as the early (TA22) gearbox, same internals. Only the TE72 one has less vent holes in the bellhousing, uses a different clutch fork and slave cylinder, has the rearward shifter, and has 4th and 5th gear switches on the housing for emissions stuff.

Got a 22 spline T50 here that came out of 1983 T-18/TE72 just to add that to the mix.

i assume they updated the later ones
