I just picked up an IRS transmission and it has the following code on it:
38
113 301 103
J
VW
AH4010755
I was wondering if anyone can tell me what the 38 and the J stand for.
I have researched the codes, and I believe it is a 4.125 gear ratio.
It also has two sideplates on it, which I remember someone telling me in the past that it means it's a 4.125 ratio.
The guy I bought it from said it came out of a '73 Super Beetle.
Are these good strong trannys? Or are the 3.88 gear trannys more durable? I have a street buggy with a tired tranny, the 3rd gear slips when I drop it into 3rd. And not to mention a couple other flaws.
And here's the dumb question, the trannys use 80-90W gear oil right?
Thanks
