i have a trans stamped as follows can't figure this one out AH 30 33 891 ???????


i can figure out ones stamped like this AT 02 03 6 produced 2nd of march 1976

The numbers after the AH are just a meaningless serial number. They dropped the counter serial number in favour of the date serial number in late 1972. Thus, your AH was made before then.

Thanks a bunch Bruce the AH is a double side cover case so i am having the AT built into a maxflyer 3.88 0.89 4th super diff and the good weddle reinforced side that should stand up behind my bunny motor for a while and drop my hiway cruise RPM just a bit

i want to try the royal purple gear oils any input???????

and yes Bruce its still snowing here in ontario supposed to get 5 cms Saturday my daughter is headed for BC next week

AH should have small diameter cross shaft AT should larger diameter cross shaft correct

Snow! People are starting to open the windows in the transit trains here.


I have one AH SSC gearbox with the large cross shaft, so you can't say all AH have the small shaft. Also, I have had DSC AT gearboxes with the big shaft.

To date a gearbox with only numbers and no letters in the code, go here:

Yep, code is AW. Same spec as above.

No.There was a plate type LSD or the more common 2 spider style. 4 spider diffs were made by a few aftermarket places with random reviews.

The factory installed ZF LSD has 4 spider gears.

So this is a good code?

CA0468993

supposed to be a bus box. Will it hold up to a stock ecotec of EJ22 Suby on a Baja 235-75 R15 tires?

Just checked the numbers on my trike and they are AH 4659. Everything I find says it's a IRS, but it's a swing axle. Any thoughts?

It is an IRS gearbox that has been converted to swing axle.
