Trunion and ball

[Frank Dinatally]

I have a 65 barracuda automatic with ball and trunion. What valve body would Interchange with it? Also it possible the trunion to be making like a rattle noise? Only when getting and off the gas. Also always thanks in advance for any help

I believe that valve body is specific to those early shift cable type transmissions. @Charrlie_S can tell us for sure, I bet. But yes, the trunnion joint can make all kinda noises. Rattles, squeaks and even a big crashing noise when the car flips over after the front of the drive shaft falls out and digs into the road. lol

65 Valiant/Barracuda is a one year only 904 trans. The valve body does not directly interchange with any other year. However, SOME 64 valve bodies can be modified to work in the 65 trans. All 65 valve bodies can be made to work in the 60-64 trans

Thanks, Charlie. I knew you would know. Do you still have that 65 904 you came and got from me in Macon years ago?

I'm not sure. I have a couple cable shifted 904's
Even have at least one full manual valve body.

The ball and trunnion has sets of needle bearings in there (the ball part) might allow for some play if they are worn. Double check the torque and play on those I would think. They have rebuild kits but you have to be very careful with the pin etc, to keep proper balance.

Anyone else have thoughts here?

One way to "test" the B&T is to remove the coupling flange at the trans. Put 2 or 3 flat washers on each stud, and reinstall the shaft. If that cures or reduces the problem, your joint is bad. Don't leave it that way. This is just to test the joint. If the boot is ripped, and the grease is gone, the joint is shot.

And I don't know if Charlie_S has done this, but I chose to NOT remove the pin when I did the rebuild tore it all down and found a good video showing how to snake the boot on without damage. Replaced the balls and needle bearings as well.

Would you share the address of the video? Thanks.

Worked pretty slick

SSHH don't tell anyone, but I have never replaced the pin. Many years ago, BC (before chevy), I did my first B&T. I could not get the old pin to budge with a 30 ton press. The pin was visibly good, so left it alone. That's what I have done on all of them.

I don't feel so bad now

Looks like more trouble than it's worth plus you might gouge a hole in the boot. I had mine on in half the time using my fingers and a half width dulled down paint stick. Lickedy split.

Cool... Yeah, worked well for me. Multiple ways to skin the cat

When you take the end "shoes" off the pin, there may be a number of selective shim washers each side, keep track of where they go. Thats how the trunion is centered.
The pin may not be centered, thats where the shims come in.

P.S.
They ran Ball and Trunion behind Max Wedges too
Good luck

Do u want a factory vb for it or a different year to work so u don’t have to use a cable? Kim

 

[Frank Dinatally]

I would love to get rid of the cables and trunion

You can use a 1966 or 1967 trans. Must be for your engine V-8 or Slant Six. Then you will need a non cable shifter, and different drive shaft. Also 1966 speedo cable. You cannot use a 1968 or newer trans unless you get a special torque converter, or have the later crank in the engine with the larger converter pilot hole (or have your crank modified)
