intermittenly won't shift out of first

[cookie2]

Well the mechanic gave me some synthetic automatic transmission fluid protectant to add to my oil to help clean the valves and stuff. Is this a good idea? Also someone told me you can use the turn the key three times and get the transmission codes but instead of being on the check engine light they are on the overdrive light. Is this true? I found these codes are they what will flash?

11 Engine RPM input
12 Output shaft sensor input
13 Vehicle speed input
14 Governor pressure sensor input
15 Throttle position sensor input
16 Transmission fluid temperature input
17 Overdrive override (control) switch input
18 System voltage
19 Internal fault in module
21 Governor pressure solenoid output
22 Overdrive solenoid output
23 Converter clutch solenoid output
24 Overdrive override (control switch) lamp output
25 Internal fault in module
26 Governor pressure sensor offset drift
55 End of code transmission

the throttle linkage is in the engine compartment, on the side of the throttle body, I had this problem in my 94 after putting in a new engine I took it for a drive and it reved really really high 5000 RPMs before it would shift. I FORGOT TO RECONNECT THE THROTTLE VALVE CABLE...

What exactly or how do you clean the throttle body and IAC?

well my FSM, says the same thing about the codes appearing on the OD light, but I have tried to check the codes myself using this method and the light never flashes, not even code 55.

I did read on the allpar web site that there are three variations on the Jeeps.

1> on-off-on-off-on
2> on-off-on-off-on-off-on-off-on
3> on-wait for the check engine light to go out-off-on-wait again-off-on

I will try the other ways.

[dksob81]

I tried all three ways and the light never comes on, I shoudl at least gt code 55. but I get nothing, hummm, I wonder what could be the cause.

I saw one wasy if you push on the odometer reset button and some other button and start car it does it? I don't know if it is on newer cars?

Well adding the synthetic oil to the transmission seems to have cured the problem. I think my governor valve was sticking. No problem for 6 weeks now .. hopefully it is fixed

GREAT to hear! So I'm guessing you want to talk about trading again? (Just kidding!)

Well now that you mention it... an even trade does seem appealing
