finally got around to getting the numbers off the panrail. PK4295887 8561 2973

linkage style

rigged where pin was

is this the adjuster screw, the one with the nut on it?

One adjustment is on the outside of the case, the other adjustment is inside the case, need to remove the pan (and maybe the valve body, can't remember).

Completely unrelated to your original question, but damn you need a real air cleaner! Youre choking that thing!

Look at your last pic. That is the band adjuster for the front band(to the left of the lever). The low band adjuster is inside the pan.

The "nut" is a lock nut to hold the adjustment in place.

Loosen the lock nut, make the adjustment with the square head. While holding the square nut in position, lock that adjustment in place with the lock nut.

It's been years since I last did this, so I'll defer to others here. A shop manual would tell you. I do know that from the numbers you listed, you'll need to determine what year 904 you have. The band adjustments are similar through the years, but not identical.
The bands are a wear item. As they wear down they get looser. The adjustment tightens them back to spec. At some point you won't be able to adjust them anymore, then its time to replace them. Won't give you quicker shifts, but should be more firm. You may not notice a difference, but the bands will be happier.

scratchinfotraction was able to let me know from the panrail #'s that it is an '84 A-904, and that it could be lockup or non-lockup b/c o f the year. I wont know for sure until after I pull the converter. Im hoping the adjustment, a fluid and filter change, and proper setup of the kickdown linkage will get me squared away.

first thing I see that needs fixed is the slot in the TPV linkage at the carb

that needs to be lengthend to fit with the pin sitting at the back of the slot

so the lever moves when the throttle moves

looks like a mess on the levers at the trans

looks like 2 levers put together or something

I am sure hope the tranz guy fixes that

with the TPV out of wack like in those pics it will kill itself in short order

not knocking on you or your car..but man thats fugly looking linkage and is the first thing we need to help you get right

at the carb on the flat bar..thats were I use 2 of them bolted together to get the slot on the throttl pin then work back to the tranz levers

yes,back the 3/4 lock nut off,run the adjsut in and snug it with a small 5/16" wrench by hand or to 72 inch pounds,back off 2 turns ,hold adjuster and lock the 3/4 nut back down

same with the low/revs band,its in the pan and can be done with VB in place

that TPV linkage and cobbled mess is deff why it shifts early and maybe has 4000rpms at 70mph

looking at the pics,I see you need a mopar throttle adaptor on the carb to get the throttle pin in the correct place

2 flat bars for bellcrank to carb adjustment to start with first

does not look like much adjustment is left on the band with only 1/2" of threds,but it might have one last time on it

I cant make out the TPV lever or the gear selctor lever to well

looks like they are mixed pieces and cobbled together some how

I got 1/2 of what you need if your guy needs some parts to go with his

its like playing I spy with your pics..post more plez

looks to be a 1 piece rod for the TPV linkage

it will have a slide block with a lock bolt and a spring on the rod with the slide block( looks like what the rubber hose and clamp are doing...)

that and 2 flat blades and throttle adaptor for the carb should fix it up some

looks like 2 TPV levers are tied together with the wire,thats not gonna work at all

I have a bunch of those that have the d hole clock in diff spots to aid in adjsuting them with a 1 piece rod

the shift linkage from the colum work ok?

cant see it in the pics

first thing I see that needs fixed is the slot in the TPV linkage at the carb. that needs to be lengthend to fit with the pin sitting at the back of the slot so the lever moves when the throttle moves

Done. After removing the TPV bracket (at the trans) from the 2bbl setup, I put the one on that came with the 4bbl kickdown linkage that I had, and that let the TPV linkage at the carb move to where it needed to be.

looks like a mess on the levers at the trans. looks like 2 levers put together or something

It was 2 of them. I feel like an idiot for that . I removed one, and put on the correct one. No more wire there.

I am sure hope the tranz guy fixes that

with the TPV out of wack like in those pics it will kill itself in short order

not knocking on you or your car..but man thats fugly looking linkage and is the first thing we need to help you get right

Yeah, it was royally screwed up, but I got it squared away with your help

at the carb on the flat bar..thats were I use 2 of them bolted together to get the slot on the throttl pin then work back to the tranz levers

Once I got the correct TPV lever on the trans, then the linkage at the carb was able to be positioned correctly without having to use 2 of those bars. I do remember someone mentioning in another thread that that was a good way to adapt a 2bbl kickdown linkage to work with a 4bbl.

Ok, I actually wont be touching this part, Im going to leave that to the trans guy so he can also let me know what he thinks about the overall condition of the trans while he's in there. I just wanted to try and tackle this linkage before I took it to him, and with the help I got here I was able to.

that TPV linkage and cobbled mess is deff why it shifts early and maybe has 4000rpms at 70mph

After adjusting some of the bends in the kickdown linkage bar, I was able to get the trans to shift properly, at the right speed and at proper rpms. I also had to adjust the placement of the slide block that connects to the TPV lever on the trans. If I had it sit on top of the lever it was hitting the trans fluid line. So I mounted it on the underside of the lever and all is well. Haven't had a chance to take it on the freeway but will report back with shift speeds/rpms, and hwy cruise rpm's.
