Didn't have time to pull the code because autozone apparently doesn't do this anymore. You have to buy it. Anyone know where I can get access to one other than buying one?

They lied to you. Auto Zone still does that around here, and I'm sure it's a company wide thing. Call around to different Auto Zones in your area. My guess is that the guy you talked to was just a fat lazy pile of shit that didn't want to do his fucking job.

+1. I've gotten this done a couple times in the last month for two different cars at two different locations.

Well, I finally took off my Kpro. My transmission shifts fine now. It must be a loose connection or something with the harness.

Are you going to fix the harness or send it to Cham to fix?

I think I'm going to fix it myself. I need some extra pins though. Do you know where to get some?

I honestly don't. I'd ask Cham if he has any that he can send you.

Ive hooked up all the sensors that need to be hooked up now. It shifts to 5th now but only when im gingerly pressing on the pedal. If I floor it, it gets stuck in 4th or if im rolling down the mountain without giving it gas. It gets stuck for like 5 min or so then shifts to 5th. Its like its waiting to make sure I don't need floor it again. Any thoughts?

Hmmmm. That's odd. What sensors weren't hooked up? I wish there was something I could do to help you out, but I just don't know enough about the harness and AT's to give you advice.

Sounds like you missed hooking up one of the clutch pressure switches or have them reversed. Check parts 9 & 19 in the link below, they are AT clutch pressure switches and are used to determine gear engagment.....

Ill have to check that out on the harness. Do you happen to know where they are paul? A,B,C,D,E connector?

Well, when I let the stock computer control idle it was kinda sketchy sometimes. Like if i lift off the throttle the rpm would drop to 1.5k and bounce once or twice to stabilize. I took pauls advice and consulted the troubleshooting manual and hooked up the MAP sensor. That stabilized the rpm when I lift the throttle now.

I've also hooked up the signal grounds 1,2 and the voltage connection 1,2. I didn't notice anything different but the temp guage is even slower to read. Could this be the problem? On the electrical diagrams I've noticed the transmission needs input on engine coolant temps. Could the guage reading slowly confuse the transmission computer? Is there a way to hook up an alternate engine coolant temp guage so I don't have to split up the signal? The hotter the car, longer the trip, the more chance of me going into 5th. Could i just have a shotty electrical connection that messes up once in a while?

When I go uphill and am in 4th gear, 10seconds or so into the climb if I don't alter any throttle input it shifts to 5th. If im lucky and don't lift the throttle too much during my trip it stays in 5th. But sometimes it will downshift to 4th no matter how gingerly I touch the throttle.

This is annoying because in 4th without the converter lockup the car is really slow even with kpro.

Well, look at what controls the ECUs decision to downshift, pressure switches/TPS if I remember right.... Also all AT specific connections are on C.

I have the stock connectors hooked up for C and D because those are what contol the auto tranny.

Ive hooked up about 5 sensors/grounds that might have been important on connector A.

is this multimeter a good one to use on the car? Can this be used on the car? http://www.licensedelectrician.com/Stor ... P-A_lg.jpg

Thanks, was just making sure everthing looks so complicated.

AND, I think the transmission sorta sorted itself out. Question is, is it possible for the stock computer to hold it in 4th until its sure im on level road? Is this normal operation of the grade logic in the PCM? I can't/don't remember if it did this stock.

Sounds like it is holding for a bit long.
