This 2005 Suzuki Reno came in with a complaint of a harsh transmission shift and the check engine light was on. I checked codes and there was one stored for the transmission but I cannot remember exactly what it was right now. I think it was P0700, no communication between the TCM and the ECM. Anyways I knew this car had been at another shop and they were trying to locate a drain on the electrical system. That will be another post. I really did not want to do the transmission diagnostics. I detest working with transmission fluid but, after looking at a wiring diagram, I decided to check the basics. The fuse box legend shows the TCM fuse to be three up from the bottom and in the middle of that row.
There was no fuse so I simply installed a new fuse, cleared the code and test drove the vehicle. All was fine. Thank goodness I did not have to do much on this problem.
I have a 2007 Reno with the same problem it was the Tramssion Position Sensor. It costs about 50.00 and it took about 45 min to replace.
I have a 2007 with the same problem Anonymous…did you ever figure out what was the problem? Seems that the car will stay in drive and not switch out even when you manually shift into other gears except Neutral or reverse.
I doubt if it is the fuse. It sounds like a much deeper problem. You should probably seek the help of a local repair shop.
I have that problem with my suzuki reno every time im driving i have the check engine light on and where it shows the letter when u switch from P to D it shows me a lil square with a line cross and then when i make a stop in the stop sign the accelarator gets hard n i got to push it slowly to drive it.. But i don’t know if that happened to u too n i don’t know if its the fuse…
