Should I spend $300 on a 67 olds SP400 trans that would be rebuilt and the tailshaft switched or buy conversion parts for my stock nonSp T400 in my 68 Riv? How much would the parts cost and is it "easy" for trans shops to do?
I think you could take the front pump and converter from the olds tranny and put it into the buick tranny. I would also think the 2 pin plug in the side of the trans would also switch over. o No:
There is also an orifaced plug that needs to go into the case behind the pump. This is the part most rebuilders don't know about. Without it, you will never have high stall. Jim Burek
Switch Pitch Conversion Cost... Ok this all sounds good, But what is required ? How many "Clams" if done at home ? Steve
Anyone have an FAQ on this subject or can write one? It would be nice to know what differentiates the non-SP and SP models. I'm very interested.
Besides the front pump(with solenoid) and orifice plug, you need the input shaft, and of course a s/p converter.
