Auto Gear Box.

[Rusty_T]

 
I was given an Auto Gear box with a 186 Engine a few months ago and have no idea what type it is. Powerglide ,hydromatic ,Trimatic, who knows?
Anyway I had a close look at it today and found the following info:
Inside the Bell Housing;

HOLDEN
CAV   No1
5258249

On the outside of the housing;

GMH
HT
E-0428618
Any assistance would be very helpful.
Cheers Rusty.

And a Merry Xmas to All.

the HT code indicates the box you have is a trimatic originally fitted to a LH Torana 202 or a HQ 202 or a HJ 202.
