Out of all automatics out there, which one can take the most beating under racing conditions only ? I am a stick person, but I am leaning towards a C4 , don't want a c6 , size and wiegh . Is anything else out there , for a high power , low wieght car ?Frank is likely thinking of my '57 racecar which has a C4 but my roadster has a PG bolted up to the Y. On the scale of power losses attributed to using an automatic transmission the PG would be considered having the least losses while the C6 would have the most. The C4 comes in close to the PG on that same scale which makes it a suitable candidate for a racing trans especially if needing a lower gear ratio for launch while still trying to maintain a suitable rear gear ratio for a quarter mile sprint. On my end the PG tranny is about a third of the cost of a built C4 or C6 but I originally started using PG's back before the technology was available to get the performance and durability from the Ford automatics. That's all changed now and as such I've got cars with PG's, C4's, and C6's.
