you can use either a c6 automatic which is probably the easiest direct bolt up match or you can buy a kit and use a chevy trans like a 700r4 which is a 4spd overdrive automatic or any chevy automatic for that matter . but if you use a 351w you can use a c4 or a c6 which are both 3spd autos c4 being light weight and c6 being heavy duty , and for manual transmissions you can use an older top loader say out of an early model mustang 1965 and later which was a 4spd non overdrive unit or you can use a SROD 4 spd overdrive from a 79 to 84 mustang which is a strong unit but not a smooth operating trans, or you can a t5 5spd or an AOD, AODE not to mention the c4,aod,srod, and t5 will all use the same driveshaft for easy of installation and require no crossmember modifications my car started out with a srod tranny and was then switched to a c4 then back to a srod and it now has a t5 out of a 94 cobra but the 94 and up t5's have a longer input shaft which will have to be change over to an earlier style input shaft but that is easy to do but you need to make sure you use an 86 to 93 bellhouse also but the 94 and upts is a much better tranny than the 86 to 93 models
