Hello all I am ne to this site and posting thing, but straight to the point I have a 2000 chevy silverado 4.3 I am getting the code P1870 and I do get a slight jump or stutter if you would once in awhile any help would be greatly appreciated thanks.

 

P1870 is transmission slipping, how many miles on the tranny? Check the fluid for low, discoloration, smell.

 

Transmission Slipping. Check the Hydraulic Pressure and transmission Unit.
