Let me start this thread by thanking towcat for catching this ad on CL that I would almost certainly have missed otherwise. I also need to thank my dispatchers at work, who somehow forgot to include me on the schedule for today, giving me a rare Saturday off and making it possible for me to run up to Vacaville to snag this before anyone else was able to. maybe my uncle's up there keeping an eye on me
For the reasonable sum of $650, I'm now the proud owner of a Doug Nash overdrive unit. The guy I bought it from said that, when he looked at it, he saw a tag saying it had been rebuilt...he wasn't sure when, but given how clean it is, I'm guessing it wasn't too long ago. I didn't have a ready source of 12 volts available at the time, so I haven't been able to test it, but it spins smoothly and he said that it shifted just fine. Hopefully all will be well!
I've been wanting to either add an OD unit or swap to 3.54's for many years...quite simply, I spend so much time cruising on the freeway that, even with the ZF, my RPM's are higher than I'd like. IMHO this gives me the best of both worlds...with the 4.10's and the F-450 tranny's lower 1st gear, I can get any load started that I want, and if my calculations are correct, I should be able to cruise at 70 mph at 1889 RPM...which is my RPM at 55 mph without the OD unit.
I'm excited and had to share ...
