unknown tranny
 

Can anyone help me i.d. this tranny? I t was attached to the rear-end of an '74 13 B rotary engine in an old Triumph TR 7 that I had.
I would like to sell it and so need to know the year and application of it. Any help welcome. Thanks

Integrated shifter and bell suggest early rx/ series 1 rx7? Not an expert on early stuff however.

That does appear to be from a 1979 to 1980 RX7.

The front one marked SA appears to be the same as your transmission. The 79-80 model RX7s are usually referred to as an SA as opposed to the 81-85 RX7 which is referred to as an FB model (rear transmission).

North american chassis codes were different but in Japan and aus, all first generation rx7s were SA22C, generally referred to in aus as s1 (integrated selector), s2 & s3 delineated by bumpers/brakes/g-box/diff/oil cooler changes between 79 & 84/5 build.
