sorry for the burden,......but wondering on the location of the trasmission type stamp. i got help on the head and block id stamps and was wondering about the tranny. i have a five speed in a 72 with 81 enigine/head. the paper trail here ends with the 81 engine and no trany. do i have an 72 five or a 81 five or what? are they the same? i have looked for this in the books and manuals but dont see the location of the stamp. i will have it on a lift soon and would like to know what i have. my manuals and books talk of the ratios and id #'s and such but not the location of the stamp. this may be self evedent when it is up in the air but would like to know where to look first. i thank you for any help. :nervous:

The site zpizzaman20 posted will help you ID your tranny. If it's a 5 speed I'm sure it's probably the one that matched the 81 engine. There is a stamp on the top of the bell housing, but unfortunately it's not a traceable number. I've run into this problem before trying to ID a tranny. It's come down to having to know what year vehicle it came out of. Especially with the ZX trannys as there's an A and B box that vary slightly on the internals, but are identical otherwise. Wlcome to the world of the Z. Not everything is cut and dry here unfortunately.
