Post Ford F53 motorhome PID Question
on: June 30, 2017 (GMT)

I would like to have a gauge in TorquePro that actively tracks what gear my 6R140 6-spd transmission is in. I have a 2016 Tiffin Allegro motorhome on a Ford F53 chassis with gas V-10 engine combined a 6R140 6-spd transmission. I had a PID that worked on my Ford 2004 chassis w/4-spd, but it no longer works on the 6-spd. Also, none of the current Ford Extended PID’s in TorquePro for monitoring current transmission gear # work on this 6-spd either. If any Ford TorquePro users have figured out a PID for this transmission, I’d sure like to hear from you. Thanks.

Have you tried looking at the Ford 6.7
pids? If my feeble memory hasn’t failed
me 221E12 comes to mind?

Current Gear
PID: 221e12
Equation A
Header: 7e1

This one works with header 7e1 as you suggested.

End Quote.

Thanks Capp777. That one is not in the Ford Extended PID list in Torque, so I guess I will have to try to add it. 1st time for everything. Do I have to include 1 and 6 as the Min/Max values, or just include the data as detailed in the link you provided. Really appreciate your continuing support.

I would leave at 0 to 100 until you
know it works. You can then edit later
if desired.

I was in the MH today and tested the 221e12 PID with the engine off but the key turned to “RUN”. The OBDLink LX was connected to the ECU and was transmitting to my Samsung tablet. I tested using the data elements previously discussed and the response was “No Data”. Then changed the Header to 7e2 as I had seen in a separate post, but response was also “No Data”. Do I need to be rolling for this PID to work given I am asking for a current gear response? I had read previously that there is some risk testing Custom PIDs on an operating engine. I’d appreciate your thoughts. Thanks.

Did you record the raw hex response
from the vehicle?

I don’t think you would have to be rolling
but I am not sure about drive vs park?

Your vehicle may require a different pid.
Did the TFT pid ever work for you?

Hi Capp777,

The response to the test of 221e12 was as follows:
Result of Equation: No Response
Command: 221e12
Response: NO DATA

For the Transmission Temp PID I am able to use, the following pertains. I did the test with the engine/trans cool this morning. At the time the trans temp reading was 73.8F.
Name: [Ford]Transmission Temp
Command: 221e1c
Response: 621E1C0174
Variables in Equation:
A=1 (hex=01, binary = 00000001)
B=116 (hex=74, binary = 01110100)
Equation Steps:
=(((SIGNED(A)*256)+B)*(9/8)+320)/10
=(((1*256)+B)*(9/8)+320)/10
=372*(9/8)+320)/10
=372*1.125+320)/10
=738.5/10
=73.85

At engine startup, this temp reading is very different from the EOT reading, but as both warm to normal operating temp, they become very similar (2-3 degrees), but with both reacting independently to the respective loads they are seeing in operation. I suspect both sensors are downstream of their relative coolers which I think would explain whey there normal temps are so similar. I was originally concerned that the 221e1c PID was not transmission related because its reading was so close to the EOT reading, but given the different reactions to respective loading and the startup differentials, I’m not so concerned about that now. In my previous motorhome, the normal operating temps for both were typically different by 10+ degrees.

Thanks for the info! The module responding
for TFT would likely be the same as current
gear if available.

What strikes me odd is the fact you are not
getting a hex response for the No Data. I
would have guessed a 7F221E12… or a
621E12…. for valid data.

You might try typing the fields again just
in case. Make sure header is 7E1 or TCM
or Auto.

OK, will do. I will test for all three headers.
Thanks

If all else fails maybe you could do
something like this…

You would need to know the specifics for your vehicle.

I ran the test again this evening after reentering all the data lines, and varying the header inputs. I had no response until when I input “Auto” into the header line, I got the following:

Result for equation: 1.0
Command 221e12
Response:621E1201
Variables used in equation:
A=1 (hex=01,binary=00000001)
Equation steps:
=A

I think that is a positive result, but I need to see what the response will be in a dynamic environment. We are heading out on a trip tomorrow and I will add the gauge to the dashboard to see what happens in operation. I will let you know.

Thanks,
Mike

Thanks for the update. Hope it
works for you.

We started our trip today. The Transmission Gear gauge worked perfectly using “Auto” in the header. Tracked gears 1 through 6 very well. Thanks Capp777 for all your help.
