46RE is the model. Not 100% on the torque converter so I will leave that up to someone else.

 

IS the 46RE the same as the 518?

 

I dont think so, I think the 46RH might be the 518.

 

For 99 it will have to be the lock up torque converter. The E stands for electronic. Though the mechanical parts may be similar to the 518 I don't know. 46RE

 

The 46RH, 46RE are basically an A-518

Not to be a prude, but I've noticed that a lot of guys are having trouble with the 46RE transmission. My '94 Ram Van has the 46RH, and it's been a great transmission with over 114,000 miles on it.

 

The Chrysler 32RH, 36RH, and 37 RH are three speed, fully automatic transmissions used in the 1500, 2500, and 3500 trucks. The 32RH is used with 3.9L and 5.2L engines. The 36RH (auto 3 spd) & RE (Overdrive) is used for heavy duty 5.2L and 5.9L engine applications. The 37RH is used with diesel and V10 engines.

A three element torque converter with a converter clutch is used with all three transmissions. The converter hub on 1993 and later models was changed to accept the new style drive flats on the oil pump inner gear. The new converter is not interchangeable with previous designs.

Converters used:
9.75" or 10.75" used with 3.9L, 5.2L, and 5.9L gas engines.
12.2" used with V10 and diesel engines.

Mopar ATF+ type 7126 Fluid is recommended. Dextron II should only be used where Mopar ATF+ is not available.

 

Take your VIN# to a dodge dealer and tell the parts guys you want a print out for your truck, i got mine and it tells you where it was originally bought and every thing it was ordered with, which tranny, which alternator, all the accessory groups..... mine was 4 pages long :rck:

 

i've got 114,000 miles on my 46re and never had a problem(knock on wood)although i change my fluid and filter as i'm told through the owners manual............

 

I posted this before, this should help your confusion....
