1983 Mirada/Cordoba and 1984-85 Chrysler 5th Avenue. 904 with 318 engine.

informative chart. Thank you!

Robert in case you wanted to know, here are the other OEM parts it should have in it. LU converter, blue-Green coded valve body with a 67 steel plate in it, a 528 transfer plate and 495 valve body, a 962 case, plain accumulator spring color, 3.2 kickdown servo lever, blue Kickdown spring, Red coded governor with narrow spool and red spring, 5 disc front clutch assembly, yellow return spring, 4 disc rear clutch assembly, 4 pinion front and rear planetary assemblies, with wide ratio.

Tom good addit'l info! I found it buried in my stash yesterday & was considering/wanting to rebuild it/race it behind this years' 360 stock car. Not sure if a LU is a good choice or not but I am assuming that it ain't.

2.74 FIRST GEAR PLANETARY ?

Wide ratio, yes. 2.67:1 or 2.74:1 depends on which Chrysler document you read. "

I've seen 2.74 alot. I gotta bone up on what the LU is/does to see if this one is an appropriate candidate for my needs.

A lock-up trans will have about 3/4" of the converter end shaft machined smooth. Chances are it is a lock-up. The valve body and pump and/or front shaft has to be changed. I don't know the specifics because JW trans always did the conversion for me. There is a visual difference between 2.45 and 2.74 gear sets also. But I don't know what that is.

Converters do not interchange without the conversion.

Since a racing converter will be a critical addition, I for sure need to convert or grab another core. I got some homework to do here.
