Kickdown cable replacement

Just finished fixing a leaky fpr last night and found that this part had broke. I didn't even know what it was till last night. Any how to on replacing this? Someone suggested I'd have to pull the side pan off...nothing I've done before so a how to would be nice. Thanks in advance

It looks like you just take that hold down bolt outta the retainer down there and pull the part that's broke off out... I think that cable presses in on something, rather that being hooked on something, see what I mean? So you just install the new one externally, I think.

Look at a new one at the parts store. Then you'll see if I'm right.

"The 3 speed will be a part # of 10085373 and goes for $42.41. The 4 speed is a part # of 10142050 and goes for $41.28."

before I order can someone confirm that I'm correct in assuming I have a 4 speed because of overdrive? Pretty sure I have Drive, OD, and two lower gears. I haven't driven the car regularly in 5 months so I'm trying to remember
