While buttoning up the interior stuff i stumbled across a new problem. The car itself is a 99 orignally T56 car, swapped to a 4L60e, in prep for a TH400 over next winter. I had some issues with the shift linkage on the car(clip that holds the cable in position was broken), so i replaced the cable with a brand new GM unit. Put trans itself in N and put shift assembly in N as well, and popped on the new cable.

Runs threw the gears okay, but the button itself is getting stuck down. I pulled the shift **** off and saw the white "stem" was not returning back up as far is it should. So i can pull the car out of part without touching the button. Also it doesnt always pop back up when shifted into gear. So i was able to pull the shifter from the park position, down to 1 and all the way back up to park about 8 out of 10 times. The other 2 it would get caught in R, but still allow me to go from 1,2,D,OD straight into reverse. None of the gear engagements felt that solid either.

I am able to put the car in say N, pull the stem up with pliers, and it will be locked out of going into R as it should. Same with putting it in R, if i pull the stem up with pliers it will function as normal.

So pretty much is there any adjustment in this? Itfeels like the stem is binding and will not freely return to the top as it should.

 

To the best of my knowledge there is no adjustment for that. It sounds like the white rod that runs through the shift lever is binding in the shift lever. You can try spraying some type lubricant down between the white rod and lever. It could be that the shift lever is bent slightly.

 

Thats exactly what is happening. Ill hit it with some lube and see what happens.

 

Hit it with some CRC Graphite lube on my lunch break, didnt make any immediate difference.
