What type of car and what engine combination is this A518 in? I'm at a crossroads trying to figure out what O/D to go with for my 69 Charger. Tired of 3000 RPM's at 60 mph. I've been looking hard at GV, however if the A518 will fit behind a 440/515 stroker in the 625 - 675 horsepower range I'm interested.

Overdrives based on the 727 are called RH46 and RE46
Rh is hydraulic governor...RE is Electronic governor that is shifted by the PCM...
Overdrives based on the 904 are RH43 with the H being Hydraulic controlled governor.

Sounds like I need to stick with the Gear Vendors direction to eliminate all of the complexity. Thanks for the info.

Overdrives based on the 904 are RH43 with the H being Hydraulic controlled governor. We never used the designation RH46 or RE46 - it was 46RE or 46RH. We went to this designation after program launch - at launch they were called 500's, 518's, 618's. We never ever offered a 43, only 42 or 44. The PCM doesn't "shift" the trans - it only controls governor pressure on the RE units - the valve body shifts the trans between gears and in to OD. On the RH it only controls the OD. Splitting hairs - not really - any of these transmissions will shift manually in to each gear except OD.

Two things to keep in mind as you decide which way to go; the Gear Vendors OD ratio is not nearly as good as the 518. .69 vs .78. That is a big deal. And the 518 is available with converter lock-up.
There are calculators that will compute the RPM difference with your particular inputs.
Now, the converter lock-up may not be happy with the full power of the big block, but that really shouldn't be an issue. How often would you want to go to wide open in OD?
The 518 probably is somewhat more complicated to find and assemble for a big block, and nearly as expensive to boot. But the better final drive ratio makes it worth the extra effort in my humble opinion. Check out the calculators and see if would be worth it to you, too.
Master, again and still
