Discuss the causes and fixes for P0700 Saturn OBDII Code

  • TCM light is on as well as the indicator light for the transmission malfunction(P0700). What is the most common solution for repair(part)

  • The P0700 code means that there is a problem with the transmission. unfortunately there are many thing that can cause problems with the transmission. You need to check for code store in the transmission control unit. With the code from the transmission you should have a better idea what the problem is.

  • i continue to have this code periodically and have found that the issue for me has been a buildup of corrosion on the negative terminal that attaches to the battery side-post and the grounds at the radiator support. Cleaning the flat lug on the cable end, and cleaning up the connections especially at the battery always seems to work for me. It starts manifesting itself as a traction control light, and spreads to multiple dash warnings for abs/esc/and even security and gauge variations along with limp mode and even no-crank issues. These cars are pretty well known for this in various forums.
