the trans I got out of my 89 Ram TBI 318 parts truck is it a 904 or 999?

I read where the lockup converter is electronicly controlled? is this true on a 89 truck? I read it somewhere on the internet

Because I had this trans looked at and cleaned at a transmission shop & im getting ready to put it into my 84 D150 with a 318 4BBL

does it have noids on the VB?

does it have a wire/sender hook up on the back of the cast by tail housing?

those would be elect lock-up

early lock up 904s like I have use hydro pressure to lock-unlock the TC.

IIRC you could swap out the VB for an early one to ditch the wire hook up on it.

as far as 904/999??? does the tailshaft have the cover for snap ring on the side or on the bottom...on the side it is a truck unit and may be a 999

get the #s on the pan rail and I will see if I can find it on my trans ID list.

hey Scratch, yeah mine does have the switch at the back above the pan rail & I just got through talking to the transmission shop, they said just to leave it unhooked that only I would have not lockup which is fine that it will just shift like a regular 3 speed & they claimed that there wouldn't hurt anything & he's built a lot of Chrysler transmissions for 40 years. He's built most of my trans when they've needed to be rebuilt, but thanks for the reply & help

I stole this link off the HAMB board, hopefully it works.
