Hi,

I'm working on a monster truck that has a chrysler driveline fitted. I'm trying to identify the Auto transmission because I want to get a aluminum pan for it and stop the leaks. It seems to have only R-N-3-2-1 and no Park. I've heard that early Chrysler had no park?? The previous owner said it had a reverse valve body, but didn't know any more about it.

Help much appreciated.

 

Lookes like a 727 to me.

 

The previous owner claimed it was a 727, but then said he didn't really know. Then looking at the oil pan it could be a 904. the 4 bolts along the back edge are in line. But again, I'm not sure and looking for help.

Any thoughts on the no park gear? The lever only clicks 5 clicks with the cable disconnected.

 

I hope I'm understanding this right, if there are 5 "clicks", then there ARE 6 positions. You have to count the one you start at.

 

Its hard to tell from the angle of the pics but I am leaning toward 904.
Break out the tape and use the chart below.

 

Thanks, I'll measure on the weekend.
Sorry, 5 positions not clicks.

Here is a pic of the Powerwagon

 

too me it looks like a 727, i can see the engine is a small block, what small block you running

 

Also unsure, I've been told but have found out the guy I bought it off had no idea about a lot of things on this truck. So here is the engine number: 2468130-7

 

Here is a working pick of the truck.

 

How come nobody took the name "Powerwagon" until now?! LOL! Figured that had been gone years ago!

 

my bad.. i saw the oil pressure sending unit and the glare off of my screen made it look like a distributor, then you gave the numbers and i had to look again, then the dizzy wasnt there,

what you have a a 383 B engine big block, so yes that tranny IS a 727,
sorry bout callin it a SB

 

So no chance it could be a 904 then? If it's behind a big block.
I did look the engine up, but being new to Mopar thought I could have been wrong.

Yeah, I was pretty happy to get Powerwagon!

 

what did you come up with? my numbers could be off, hell i thought it was a SB when i 1st looked at it,
BB were 727 only if it was an auto,
i dont feel that embarrassed cause no one else thought to look for a dizzy in the rear of the engine,

 

It is a BB motor based on looking at the frist pic. Also, I said 727 because of a thread that blue 68 gt posted up a while back - https://moparforums.com/forums/f62/7...mparison-6092/

You can see in the first pic there are no "ribs" coming down on the back right side as there is with a 904 (see picture).
