915 Type Trans

[3.2 CAB]

Does anyone know what the actual differences are between a 915/67 and 915/68 5spd transmissions? I know the Red Book states the 67 is a ROW Carrera, while the 68 is U.S, Canada, Japan Carrera. I am trying to find out what is the actual mechanical, gear, gear ratio, etc. would be, that is if anyone does know. Thanks.

915/67 has an external oil cooler standard

Thanks a lot Bill. The biggest difference looks like the oil cooler. Would the ratio differences have much effect on the performance between the two? To me it looks like the type 915/67 would let the engine have a lower rpm for say, 70 mph, or any other high speed, than the 915/68 would. Does not look like much though. Tony.
