Post subject:  Shift linkage dilemma

I have a 1967 Dart GT equipped with a 904, and console shifter. The car was assembled on September 1, 1966, the 11,138th unit down the line for the 1967 build year. The transmission is 1976-77 vintage, and the block was cast in 1968.

Lately I have been having a problem with the "lower rod" connecting the "vertical torque shaft" that passes down through the floor from the console shifter to the "transmission control lever" disengaging randomly from the "transmission control lever". When this irksome event takes place, I have to squeeze under the car, and blindly reconnect the rod that resides just above one of the more often than not, HOT exhaust pipes.

After examining the factory manual today I discovered that the vertical shaft looks to be from a 67' Coronet, and an oddly shaped rod from an unknown model not like the Dart & Coronet rods shown in the factory manual. I was wondering if the linkage for 1966 Dart was different from 1967, and perhaps my car being an early build was fitted thusly.

The connecting rod on my unit has a "swivel assembly"(adjustment device made up of a bolt holding the rod) located on the "torque shaft" attachment point, and a press fit into a small hard rubber socket less provision for a cotter pin on the "transmission control lever" end of the rod, the end that pops out.

Can someone out there in Slant Land help me identify this mess, and suggest a solution? I would like to get this linkage problem corrected before the car goes to the transmission shop to be relived of an annoying reverse valve body, and other internal repairs. I work cheep, the trans guy not so cheep if you get my drift.

Just got back from a successful test drive, and now a recovering victim of "Budweiser Engineering" by the previous owners.

Per usual, too much thinking, and not enough wrenching around going on around here. The linkage problem is now repaired using all the parts that were hanging off the "Frankindart" plus a few new washers & cotter pins.

I flipped the rod end for end, relocated the adjustment clamp on the control lever after modifying its rubber bushing, and mounted the other end with a washer and secured it with a cotter pin. Apparently the later transmissions used a different type of rod or cable attachment than the 67's. My 82' Lebaron has the same rubber style rubber bushings, but smaller.

That part ain't gonnah pop apart again...
