I do have a Td5 pedal complements of surf110. I took initial resistance measurements of both the GM Silverado pedal and the TD5. I have yet to graph these in Excel to verify the both pedals have the correct ratios. I also have to locate the proper connector to mate to the GM harness for an adapter to the TD5. I will get to it, just don't have time right now. The TD5 pedal doesn't just bolt in. Different pattern.

The Lokar actuator is manufactured by Williams Controls and is a Hall Effect device. No potentiometers to wear out. Williams Controls supply the mobile industrial community. CAT, John Deer, ...

No changes required. Comes with the correct GM connector. Just plug it in and start it up.

Of course, many wives-mine included, don't know the first thing about our gas mileage.

If I told her the "old" motor got 5 mpg and this "new" LS gets 30mpg, she'd say "well I guess that's better; good thing you did it..."




Now, to make sure I don't leave this page up in the kitchen...

From what I recall, the GM and TD5 potentiometers are very similiar, I don't see why with a little work, the GM couldn't be adapted to the TD5 pedal assembly itself.

Are you referring to the two track or three track Td5 pedal. I believe the two track (the one I have) is wired like the GM. Two potentiometers with different slopes. Both wired to produce positive voltage on actuation. (0-5vdc) The three track Td5 has one pot wired in reverse as a means of verification.

After all that, we need to see what the pedal response is like. It may still throw a code. We will have to see. Anyone have more info on this?

I think I found the GM mating connector at Mouser, 15326833

Is it possible to convert the car transmission to 4x4 by swapping out the tailhousing?

You will have to change the tail housing to the 4x4 case adapter for sure. (~$98 new) ...and replace the output shaft on the transmission. That requires disassembling the transmission by a transmission shop. Usually costs about $250 plus the new 4x4 shaft.

At that point, you could ship me your ECU and TCU/valve body out of the trans for reprogramming.

Not sure if it will help anyone but there is a sticker with the different codes on the vehicle that you can use to find out a little more information.

For example the code for the 6l80e transmission is MYC
The motor code is also listed on this sticker in the case of the one show here LC9

I found it helpful when looking on ebay as many of the dismantlers post a pic of the sticker so I could at least know what motor/ trans and then just needed to figure out if it was 4x4 or not.

You should be able to calibrate the pedal to the ECU? All you need to do is let the ECU know where closed throttle and open throttle is and Bob's your Aunty?

My roommate in college did an 8100 swap in an 80s pickup truck and I remember it didn't run with the first pedal and pedal module combination. There is some split and not all were compatabile though they had the same part number on it. I do remember measuring 3 pots on it that all worked.

That's the build sheet sticker showing all the "options" added to that truck at the factory. Eg z71 is one most folk know.

Motor arrived a few days ago

LC9 5.3L w 4x4 6L80e purchased as a lift out package with 40k miles came with the harness and ecu as well but I removed them already to send off to speartech to turn into a stand alone harness.
