95 Ford Contour buckin and kickin

[driver540]

95 Contour 2.0 zetech auto trans

Car is buckin and kickin intermittently at highway speeds. Kicks out of gear as if in neutral, shifts up and down between gears. Have pulled some codes with my "brick" and I of course am not a tranny specialist. Here are the codes that I pulled


335 code def not available
332 EGR not opening
461 code def not available
668 transmission range sensor circuit high

Any ideas? Of course I saw the tranny code, but I dont work on transmissions. Will swap and service but no repairs.

Do you have a TR/MLP tester??
Really sounds like you have a bad MLP. or a bad or shorted circuit for the MLP,
that comes from the ing switch and the PCM you can check this with a "digital" ohm meter.

Let us know what you find as far as values .

Your code PO 461 breaks down to the VDF solenoid, but being a 95 I don't think,
this vehicle came with a VDF.
as far as the code PO 335, are you sure it couldn't of been PO 355 ?
according to the systems you stated , PO355 makes more a more plausible code.

According to my outdated Snap-On "brick" it spit out 335 code a few times instead of 355. Anyway, I am still waiting for the guy to decide if he wants to try the repairs suggested or not. Kinda draggin his feet after hounding me to look at it for a week or so. :roll:

Will post up as soon as I find something. Thanks for the reply.
