Shifting Probs - Revs to 4k before shifting gears (Daily Driver) November 11, 2009, 06:50:30 PM Hello,I have an 88 XR-7, stock, that has just recently had a problem of getting up to high RPM before shifting. Normally it shifts at/around 2200rpm but lately, out of nowhere, it started to not shift until 3000. After a couple days, it seemed to fix itself so I kept driving it. Now, it has come back and seems to be worse (will not shift until 3500rpms or so). It is shifting harder than normal, but I think it is because if the RPM its at. It is the same for all gears, not just 1st or 2nd, so I'm guessing its not a tranny problem...I ran the self test with the following results:KOEO:31 - PFE or EVP intermittent failure63 - TPS circuit below min value 0.6vKOER:18 - SPOUT open or spark angle word failure21 - ECT out of range (yes, i let it warm up before testing)45 - Thermactor 2ndary air misdirectedI was recently doing some dizzy and timing work after pulling the dizzy to replace the thermostat and received the code 21 so it might still be a problem, but I'm not sure it has anything to do with the shifting problem.Can anyone tell me if they have had this problem or if the codes I pulled could be causing the problem? I was reading it might be the cable to the tranny but I am not that savvy with AOD. Thanks in advance!! Quote Selected

Shifting Probs - Revs to 4k before shifting gears (Daily Driver) Reply #6 – November 12, 2009, 05:49:03 AM Like others have said, check the TV cable at the throttle body. The plastic bushing there gets brittle and breaks. If it's broken replace it with a metal one. Also check the TV cable linkage on the tranny. If the lever is sticking the tranny will behave like you're at WOT all the time (late, hard shifts) Quote Selected

It will be plastic and squareish the bushing/grommet might be white. Quote Selected

Shifting Probs - Revs to 4k before shifting gears (Daily Driver) Reply #12 – November 13, 2009, 01:05:29 PM Ok so I accidentally broke the rail on the throttle cable bracket part of the TV (kickdown) cable...Anyone know where the best place to find one is? Junkyard I'm guessing...Also, There is a problem with the throttle cable, so as I am removing it, I can see one end goes to the gas pedal and the other goes into the body of the driver's side fender...WHERE DOES THAT GO? I can not locate it for the death of me...Also, I believe that the pedal cable has a crimp on it to keep it from being sloppy that is not doing its job...easiest repair? Quote Selected

You can still get NOS TV cables from some dealers around the country (last time I checked there were about 10 dealers that still had one, after I bought mine it's down to 9). They cost $95 for a new one. Quote Selected
