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

Thanks all for your input. My build is too far down the road to do any cutting in the tunnel or change the transmission mount. Had I caught it earlier I might have done it. The 518 non lockup would have been a good choice but the parasitic losses are really more than I care to tolerate, being a mild build 273 and all. I am not interested in the 6 speed split shift thing either, just want a nice highway cruiser using my new 3.73:1 rear gearset. I am going ahead with my 904-Transgo-2 build with the gearvendors unit. All stock mounting works without modification (clearance top bolts in tunnel) and I understand the schematic and function of the unit. GV sent me the installation manual and schematic even though I haven't ordered it yet. More money but I get what I want this way. The transmission shop guy led me to believe the 518 would be a bolt-in and got me excited. You all have been great in chiming in and I appreciate it, thank you!
Can you say Power Tour 2017?------Cheers to all, DR:coffee2:
