I thought about using an aftermarket deal for my setup. I'm really not all that comfortable with what I had to do, which is extend my kickdown to the very last two thread and rebend it by hand to get the correct angle. I'm running a Performer RPM intake (a very tall 2-plane) with a 1" carb spacer. It is working for now but I'll likely take a piece of all thread, cut the kickdown part that is at the carb, and make my own linkage with the right geometry. I've also heard the Lokar is a PITA but do not have personal experience. What these folks do: http://www.bouchillonperformance.com/looks like one heck of a product but is out of my redneck/grass roots/phd student price range (yeah, I know those things don't normally go together, but...).

you can rob most of that bosh set up from a 93 5.2 magnum Dak its all the same thing but the bosh kit comes with a intake bracket and throttle lever adaptor thats all thats need after getting the dak set up from a jy IIRC they will sell just the bracket and lever I read that you can use a Dak cable from a dealer as a replacement that got me to thinking and was looking at the whole set up fro a dak it looks all the same to me,just need the bracket and throttle adaptor for the holley/eddy carbs its set up to give the correct lever ratio for the older 727/904 trannys which the new od units are based on

Driving short distances at light throttle with the TP linkage inop isn't that big of a deal.
If the trans won't shift from 2nd to 3rd with the TP linkage removed, the linkage isn't the problem; with the TP linkage removed the trans should shift 1-2-3 almost immediately.

Late upshifts and uncommanded downshifts mean the linkage is too long, shorten it up and it should shift at the proper road speeds.
Chilort mentioned something that I hadn't thought of, the original problem might have been soft shifts masking one of the shifts, it was actually shifting to 3rd but one of the shifts wasn't felt.

I shortened my kickdown up as short as possible and thought I had this fixed. Until today took the car out to get my historic plates before work and trans worked ok. The shift from 2nd to third seemed a little lazy but it shifted so I was happy. Trip to the liscense office is maybe 5 miles or so. Car sat for about 20 minutes while I did my paperwork and when I went to come home it wont shift out of 2nd gear again. Any ideas where to look? Would this seem lke something sticking in the valve body? I really need to get this straightened out its driving me nuts.....Thanks in advance
Similar symptoms can result from having the wrong filter installed or some other cause of fluid blockage. Is the 727 year correct for your car? Might be time to drop the pan and take a look see.
Good luck.
