4l60e vs 4l80e = problems I finished my 60e to 80e swap in my '06 Silverado but now I have some problems maybe you guys can help me with. It shifts smooth and all gears seem to work normal. Here are my problems I noticed during my one short drive..
1. P1810
2. The torque converter would try to lock for a split second then unlock.
3. The 3600 stall is acting more like a 2500 stall.
4. If I hold the brake and give it gas it sounds like the converter disc or something is slipping or dragging. Also I cannot get they rear tires to spin while doing this.
5. There is a whining noise when taking off.
6. There is a whistling noise when truck is stopped and in gear.
Also the truck itself sounds totally different now then it did with the 60e, like I lost all power.
I have hptuners but I'm new to it. Does anyone have any suggestions? I did the segment swap and wiring myself.
Here is a video of some noises.

Is your trans being controlled by the original 2006 4l60e TCM or did you modify some how to control it like earlier transmissions controlled by the PCM?

I did a 4l80e segment swap. Today I 100% verified that the transmission came from the local junkyard and the guy I bought it from is a liar. I put less than 10 miles on the transmission and the fluid is already black!! It needs a complete rebuild, that's my verdict. I just pray I didn't hurt my brand new billet FTI converter.
