I have a turbocharged S10 with 4.3/4L60E. Off the line doesn't feel as strong as it used to in the past, and the high end shifts are weak.
The power delivery is not very linear, so how can I tell if my issue is power related or if my trans may be slipping?
I cannot find anything in the scan logs which seem to indicate anything about the trans. Anything I can/should be watching?
Maybe scan TCC Slip.
I'm just throwing an idea around. I'm not sure if TCC slip is relevant towards your inquiry.
In my scans as I go into full throttle I see around 500 rpm tcc slip, and the longer I hold full throttle the lower the TCC slip is regardless of gear shifting.
But if your RPM climb but truck is not pulling, it might also be fuel related. Hook up a wideband if you haven't already.
I don't see TCC Slip anywhere in my collected logs. Options seem slim with a Chevy 4.3Quote:

That's pretty much what I'm trying to find out, how I verify if it is slipping.Quote:
