I have a 2003 Chevy Cavalier LS with 140000 miles on it with an automatic transmission. I had a problem a couple days ago that it was throwing a check engine code of p1860 and my car was stuck in 2nd gear with no traction control. Replaced a blown fuse and car worked perfectly. Fast forward to today when it downshifts and is now stuck in 1st gear with the traction control light turned on, but no check engine light. I checked all fuses and none are blown. I have P R and D. Low gears 1-3 don’t work and in drive I only have 1st gear.
Hi, Here’s what a P1860 codes relates to. Maybe you should check the transmission fluid level (also cleanliness of the fluid - does it smell burnt?) and also the fluid filter. The fluid and filter should be changed every 50,000 miles
