Yes, on a 93 voltage is controlled by the PCM. However, it is very possible someone modified it and switched it back to the old style. Check your firewall left of the last cylinder.

johnny08

Swap theouter wires on the pot.. I have mine almost all the way counter cw.

johnny08

If that wont work maybe check the linkage fix. On the how too section.

I have changed the outside wires on the pot I even purchased a new pot tried it again does my voltage need to be wright going to the old pot I messed with the 10mm tps screw before I tried the pot idea do I need to put it back to proper volt readings in order to make the new pot wrk

johnny08

The old tps shouldn't be connected to anything once you install a pot .. did you disconnect the wire from the tps? Or have you ran the wires from the tps to the pot? This wont work at all. ..

Yea they the wires are not connected to the old pot at all I made some adj to the 10 mm tps adj nut before I put in the pot from radio shack I was wondering if that would be part of my prob I don't think so just wondering my tv cable looks good thanks for your good ideas

My potentiometer is very sensitive, and it's supposed to be linear taper (not an audio one, that is log rhythmic). If I go all the way to the left, or all the way to the right it won't go in OD. I have mine set up so mid stroke is exactly pointing up.... I keep the dial pointed at about 9 o clock and just the smallest bump will change it.

Like I said... all the way to one way or the other and it won't work, and it seems to react sluggish... as in you can't just slowly rotate the **** at 50mph and feel it shift. It's delayed by a second or two.

I I think it might be another sensor somewhere does anybody know what it could be I have replaced the tps sensor speed od sensors ? Thanks for your help

1cowboy

I here the is a govner sen or something like that that might be affecting the od ? What do u think

Onemoparnut

There is a temp sensor in the trans line that could cause it. Try unplugging it and jump the two wires together and see what happens.

Also if you test the 2 wires at the od selonoid for power and ground the wire that is not hot through a switch od should work unless the problem in in the trans.

When they connect the the computer to it they r thinking it us a internal selonid for 4 th gear would this test let me know that! were is the od selonid thanks again I know I am green at this thanks again for your help
