Transmission problem
1999 Buick Park Avenue 6 cyl Automatic 163000 miles

My check engine light goes off often. When it does it seems as if the transmission hesitates switching gears. When I decelerate, it downshifts very hard & I can feel this toward the rear of the car. I did a diagnosis & was told it's a speed sensor. Where is the speed sensor located? Is it on the inside or the outside?

I gave you the information for the output sensor that's what people call the speed sensor. Now the input speed sensor is inside the transmission. If you can tell me the exact name of the sensor they are talking about changing I can tell you more. Call and ask them then post the information so I can give you the correct information.

Well I guess it is the input sensor the codes that came up he said was p0716 & 717, do you have a diagram for changing that one? There were 2 other codes that came up as well, p1546 & p1602, my air conditioning isn't working so what could this be? Can you please explain these other 2 codes? Thanks so much!

I emailed you how to replace the input speed sensor. The labor for replacing the input speed sensor is 4.1hrs times what ever the shop labor rate is 80-100 per hr?Plus alignment 60-100. For your other two code's I need to know what the 8th digit of your vin is?The transmission's are same for both engine's but I need to know what the 8th digit of your vin is so I can get you the correct info.I think it has something to do with your a/c.
