2006 nissan altima 2.5 speed sensor
my car was not changing gears, so because of that no matter how much I pushed in the gas pedal it would not go any faster than 20 mph. My mechanic said I needed to replace transmission but after just replacing that sensor the problem was solve. That sensor saved me a lot of money. Yes I recoment people buying sensors before buying a transmission

Great replacement part
Dealer said part was on back order, checked 1a Auto they had it and also had an install video. Love the how to videos. Helps a lot for the DIY people. Easy to install and works great. Transmission shifts great and speedo works normal.

Good fit , good price.
You pay an arm and a leg to buy parts from the dealership. I bought this sensor from A1 auto for much cheaper and it fits exactly like the original. I recommend buying it with no regret. ??
