I logged all the trans pids I thought would tell the tell but I don't know what to look for Which pid in hp tuners will tell the tale? This is in my crew and it's a stock 80e,stock stall with a pretty aggressive tune. It still barks second at wot but it will flare rpms before the shift,feels like it doing it on the 3-4 shift also. Thanks

 

Upload the log file.

You want to look at trans input rpm compared to output rpm. These should be seperated by the trans ratios, 2.48, 1.48, 1, .75. You will see the torque converter by comparing engine rpm to trans input rpm.

 

Man you've helped me a bunch...Thanks!! I didn't save the log this morning but I will log again on the way home.

 

Actually 4th will still be 1:1 comparing ISS to VSS rpms, as the ISS is after the overdrive planetary.

 

Ah, good catch. I use the VSS on my transfer case, so mine is correct.

 

Here is the log and config I was using.trans slip.hpl

trans pid.cfg

 

35-37sec into the log. that's a slip for sure

 

Yeah that's what I'm afraid of...I'm not pissed if it needs building because it's first 85,000 was behind a damn 16 passenger 3500hd bus lol. I have beat the **** out of it for the last 10,000 in the crew. May bring it down to Trussville if I can get a deal on a rebuild

 

haha well i know a guy if you need some help

 

Got around to pulling the pan today and I was pleased to see no shavings...but the pan is full of graphite looking material?? lockup clutches?? I cut the filter open and found some small black particles, the fluid smells burnt but doesn't look metallic
