4L60E SES Code
4L60E SES Code I scanned the code the other day and it came up as ENHANCED DTC 1860 I think thats what it was. Another thing is that when your driving it shifts hard from 1st to 2nd and sometimes to other gears. It only does it periodically and not all the time does it throw the code. If anyone can help I would appriciate it thanks. 1SICSS

My tranny started shifting REALLY hard on the 1-2 shift when driving around town. About 9 months later and a few dragstrip trips, I lost my 2-3 shift at WOT. The car simply would NOT shift out of 2nd going down the track. Well, now 4th gear is gone and the rest are slipping REALLY bad. I don't know if the hard shifts on your trans MEANs that your tranny is on the way out, but mine did. Good luck!

You need to know if its a P or C code.
Either way it appears you have a bad solonoid or a short in the trans.
