4l60e Clicking
Was not sure exactly what form to post this is so trying here.
Info:
88 IROCZ with ls1 and 4l60e
896 PCM
This is a new build and i have not started the car up yet. Just finished doing all of the wiring.
This is all with just accessory power on.
When i turned accessory power on the first time I did not hear any clicking from the trans. But that was with the stock tune of the 99 camaro ss Manual trans that the pcm came from.
I changed the tune in HPTuners to a 4l60e trans and copied over all the values for a stock transmission from a stock tune file.
Once it finished writing the file the clicking noise started.
I rechecked my tune and made a few minor changes and when it was writing the file it stopped clicking, but when it was finished it started again.
So my question is what makes that clicking noise in the transmission that is controlled by the PCM?
It is possible that i have the pins mixed up going from the trans to the PCM.
Video of the sound
