I got a 2000 ZR2 and im not for sure if it shifts at the right RPMs. It seems to go up too many RPMs before shifting, and I was just wondering if this is apart of the ZR2 system or if it is a problem. It has the stock 373 gears. It shifts into 2nd at about 3300, 3rd at 3100, 4th at 3000, and overdrive at about 2500. This is if I apply normal acceleration, and when it shifts into overdrive I'm running about 60 MPH (this is not due to me being a "leadfoot" i actually am very soft when it comes to driving). As you might think if I accelerate like this i get horrible gas mileage, so at about 2200 RPMs in every gear I simply let out of the accelerator at it will shift. Any comments will be greatly appreacitaded!

 

deffintly not a zr2 thing, something doesnt sound quite right to me.

 

If you are in 2W and you drive conservatively, it should shift into all gears at or below 2,000RPM. I do it when I conserving gas lol.

 

yeah i know something is wrong but i have no idea what. and yes i do drive conservately but it still does it.....

 

Could be the previous owner changed the shift points from stock.

 

how is that done?? isnt everything ran through the computer?? and what should i do and where should i go to get it looked at??

 

I took my ZR2 to a shop and got it scanned and a TP Sensor came up....changed it today and it runs like new!!
