Talked to my transmission guy-------

I was going to build my 904 with a gearvendors and the transmission guy suggested a 1990 518/727 2 wire non lockup transmission he could build for me that would be better than a gearvendors unit. I did the search routine and couldn't determine if anyone has acutally done this change. Could use a little input here, such as how it wires and controls up and down. It would be less than half of the 904/gearvendors with a warranty and seems like the way to go. My rear axle is an 8 1/4 with 3:71 SG unit brand new by RRP. Please chime in if you have an opinion good or bad.
Thanks, DR:burnout:O:)
