Code P0717 Tip

The tip on this code is for chevy and Gmc models 2007 and up that are equipped with there own Transmission Control Module or TCM, this will not work on vehicles equipped with a Pcm,

[@davidc9286]

I emailed Gary and he promptly responded with the correct TCM wire color for my 2012 Chevy Colorado 1LT 4x4 Crew Cab. I ran ground wires with crimped connectors to the closest factory ground and crimped replacement wire to the correct colored wire that was provided by Gary for this grounding problem from the input speed shaft sensor. Buttoned everything up. Took my truck on a 30 mile test drive. The P0717 code is gone. Chevy dealer wanted $199. just to diagnose. Cost of wire, connectors, and the butt connectors was less than $15. Took an hour to get it done. THANKS GARY !!!

[@hki7011]

I have a hard shift from 1st to 2nd and had two Ammco transmission dealers look at it: one said needs transmission change, the other said it is a speed sensor, but would not guarantee it would fix it and suggested transmission change. So I changed the 1-2 solenoid, no help. I slaved in a TCM, no help. So I am down to the ISS. Then send to an automotive place and they came back with: codes P0700, PO716, PO717 and they wrote: "live data scan found input shaft speed sensor (ISS) reading zero rpms.wiring from TCM to transmission show no open short at this time. So do you think the ISS will fix the problem? 2012 CHEVROLET SLVR 1500 VIN 1GCNCPEX0CZ273113

Hi Gary, i have 07 suburban , i have grounded the iss wire and still have an intermtent issue with harsh shifting in 1 to 2 gear:. I got a junkyard tcm tried that same thing, runs good then all of a sudden hard shift in 1 to 2 gear. I checked continuity from tcm pins to the trans plug seems ok, any ideas? Yes it throws p0700 then p0717 if i let it go. Could it be connections in the trans it is the 4l60e??? Thanks.. ps. If i shut it off then restart it usually returns to normal most of the time.. i only saw it not reading the iss 1 time when i hooked up my alltell,

Had to do this on mine this weekend. Wasn’t too bad. Mine had p0717, hard 1-2 shift, cruising around 45mph the rpm’s would fluctuate a lot I believe because the tcc was going in and out. And my wife says the car would stall in the intersection.

08 pathfinder v6 p0717 vibration at 45 and up. Hard acceleration rpm goes all the way up. Normal driving random hard shifts. Replaced tcu did nothing. Bad trans? Bad torque converter? 160k miles should I fix or look for better vehicle don't have much money only vehicle ha what would you do in my situation?

[@GaryFerraro]

check fluid level, if you can clear the code and see what comes back. May have a few problems, the P0717 code could be a bad input speed sensor located on the TCM which is bolted to the valvebody, if bad you would need to replace the valvebody/TCM. The vibration could be a Torque converter chatter does it feel like your driving over railroad tracks or maybe like a washboard effect?
