Where is the best place to have a A518 trans supplied and built. No one in Australia has one.

The a518 is sometimes called a 46RH. You might search for that also.

I did not know that 46RH was another name for the 518. Thanks for that.

I make a trans brake & reverse manual valve body for the 518.

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.

Cars never received any of the overdrive, just truck.

All overdrives used the small block bellhousings except the diesel and they had a unique bellhousing which only fit the diesel and V-10. Some people continue to say they are a big block bell but that is incorrect. The diesel and V-10 received 12-3/4" converters and had a radiuesd shaped cutout at the bottom of the bell.

To fit a big block you need an adapter or have someone transplant a big block bell to your trans.

Overdrives based on the light duty 904/998/999 are called A500.
Overdrives based on the 727 are called either A518/618.

All the overdrives units look very similar to each other but those used behind diesels received a different spline angle for a few model years (so be careful mixing parts up) and some used single sided overdrive clutch discs (we eventually went back to dual sided).

Each family was first released as non-lockup then eventually made in to lockup.

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.

Or put a third peddle and a 5spd in it.

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.

I want the four speed for my dually pickup which will be a daily driver and sometimes used for towing. Motor is a stockish 318. Diff is dana 70 which is being rebuilt at the moment with a power lok and 3.54 R&P

If a stock engine and not towing much weight you may want to consider one of two things.

Use the A500/42-44RH so you get the 2.7 first gear with that 3.54 rear.
Or move up to a 3.7 or 4.1 rear with the A518/46RH.

I have an extended cab 93 diesel with 3.54 rear and 47 w/o lockup - it can haul 9000+ lbs but it labors from a standstill and I have to stay out of overdrive up long grades or get a good running start.

I'm converting the trans to lockup this spring but moving to a 3.7 or 4.1 axle so I can carry more weight and get away from the light a little easier and leave it in overdrive.

Will the A518 trans survive a 700 hp engine in a 68 B body?

To the same level that a properly built 727 will- provided you don't hot rod it with OD engaged. Transmissions are really rated on torque output not horsepower anyways.

Pro Trans builds and has the adapters to put a 518/46RH behind a big block. Darren is installing one in his Coronet project. They have picts on their Facebook page from Sept 13.
