whats tranny code 15? and how do i fix it

[JoshM]

Code 15 = Kick down switch circuit shorted.

Let me do a little searching and I'll get back to you with how to fix it.

Edit: Couldn't find any info on fixing the problem, sorry.

good lookin out though

just find the wires going to your kickdown switch and see which ones got the casing pulled back or pinched, does the car kickdown fine?

its having trouble shifting, it wants to redline, unless i ease off the gas a lil then it shifts, i changed the tranny oil and it helped a lil but not that much

I don't know where you got that info — code 3 is throttle angle/kickdown sensor, code 15 is NM/intermediate shaft speed sensor.

Look on pages 9-50 and 9-22 for instructions and diagrams .

and where is the kickdown switch anyway

[Potatoswatter]

The throttle angle sensor is on the throttle body according to the diagram. However you can easily follow the throttle cable down to a lever on the front of the AT, which is what I'd call the kickdown cable, and I assumed that was the mechanical kickdown switch.

theres no wires running to it, so how could it be shorted?

speaking of if I did get a code 3

[Potatoswatter]

Yeah, I never saw wires there either, but that's what page 9-22 of the manual shows. Why I said "according to the diagram." I never really looked, anyway.

Thanks. I can't tell if he's joking or why he would post that if he doesn't have an AT.

i'm throwing tranny codes 14 and 15
i just got back from a tranny shop and afer diagnosing and taking it for a test ride, they told me that 2nd gear is gone and my tranny is gonna have to be dropped and rebuilt this is a prelude tranny i got from hmotors now should i have it rebuilt or just get another tranny?

[Potatoswatter]

Shop around and get estimates for both… I can't imagine rebuilding an AT with 150000+, but I don't know very much.

Amazing you can get around without 2nd gear tho! But as long as you can use it, shop around I guess.
