Reply to "RBT transmissions...any experience with them?"

What I think I know: RBT Transmissions is THE place to have ZF work done. The business was started by Roy Butfoy and his son Lloyd under Ford auspices when the Pantera was new. They were trained in ZF work by the Factory in Germany. When ZF decided to stop making the 5DS-25/x model in the mid-80s, RBT bought the U.S. (and maybe the world) rights, all the tooling and spare parts, engineering dwgs etc. So, 100% of the new parts, gaskets etc marked 'ZF' come from RBT, and other Pantera vendors buy them for resale. Other (used) ZF parts come from cannibalized transaxles not economically repairable or from redesigned cheaper parts others have made.Its up to you whether you want such in your tranny or not. Nearly always, its a money decision as to who does one's ZF work in the U.S. but if the parts installed are new and genuine ZF, they will be RBT parts. Caveat Emptor! I have not personally had ZF work done at RBT, but then, I've also not NEEDED to have any work at all done (beyond safety-wiring new ring gear bolts).
