Transmission not shifting


Asked by Iowa Mar 09, 2013 at 11:04 PM about the 2006 Suzuki Forenza

Question type: Maintenance & Repair

i have i 2006 suzuki forenza with 102000 miles and just recently my transmission started acting up. I tried to pull away from a stop light and it took more acceleration than normal to go. Then i realized the check engine light was on. Not sure if it's stuck in a certain gear or not but it doesn't shift. i was going about 55 or 60 at about 3000 rpm's when normally it would only be about 2000. At first i thought maybe it could be low on fluid, but im not able to just check the fluid since there is no dipstick. It also shifts hard when going from park to reverse or from neutral to drive. It does start and run just fine so I'm not sure if it's a sensor. Is this my transmission beginning to burn up or (hopefully) a simple fix that won't cost 3000 or more dollars to fix?

It's your Transmission Range Sensor. It'll cost between 200-300 for a service tech to replace it. Your actual transmission should be fine. Make sure you take it to an actual Suzuki Repair center, as my normal mechanic couldn't get it right, and I went through a few of them before I had it put on correctly.

I had the same problem, it is the trs ... found repair videos on u tube, I marked where the old one was on the top bolt with a sharpie as it has to be put in with an alignment tool, u can do it yourself without the tool, the part is around 40 bucks, took me 45 minutes and it worked on the first try! I watched many videos though,
