My Th350 needs a detent cable. And more importantly, I do. It and the engine run very good but no passing gear and risking popping it into 1st (did that once with the V6 and 200 metric. Hilarious, but not this time with this combo.) going up a steep hill at 40mph. I've searched and searched, and I cannot find the CORRECT length. Don't want to go through all that trouble and have it be too short or way too long. Who knows the part # for the right length? People who have done this please chime in.

why would they come in different lengths, the distance from the transmission to the carb doesn't change in each car even if it's V8 or a V6

They do come in different lengths. Some are 33 inches, others are up to 50 inches and one is adjustable from 28 to 48 and I have no idea what that means. How is it adjustable? Everytime I try to get one online or from a store I have no idea which size to get. There's like 50 different ones. And my car, well drivetrain never came with one. All for just the TH350.

The carb in a V6 is basically in the same position as a carb on a V8, the detent cable attaches to the TH 350 transmission in the same place on each transmission so unless it's on a custom application they should all be the same length

they don't come in different sizes if you buy an OEM style detent cable, if you look as this ad there is only one for a TH350.The adjustable one is a universal temporary fix.

So I take it that CA1951 is the one I need then. I hope that one will have the same end on it as the similar one I found at my local yard. Shame i couldn't get to any of these. EVERY single 80s gm that had anything left was swarming with wasps. And grasshoppers for some reason. Whole yard is full of them. Size of your thumb. But yeah, no cable is worth wasps. I did manage to take a picture of my linkage (with the stupid V6 bracket) and the cable end I think I need, which is the same as that part number.
