Why does your 01 Volvo s60 hesitste when you stop and then excelerate?

Answer 1

Your Volvo has an older version of the Transmission Control Unit (TCU) Software. When you apply the brakes and come to a complete stop, the transmission will automatically go into neutral to reduce harmful exhaust emissions. To fix this issue, you need to take your car to your local Volvo dealership. Have them update the TCU software, and your Volvo will stop hesitating. The cost should be around USD$45.00 + 1 Hour labor + Taxes. Volvo dealers commonly charge USD$80-120 per hour for labor and taxes vary depending on your location.

If that does not resolve your problem, have the dealer flush and fill your transmission with clean fluid. Have this done ONLY if your Volvo has LESS THAN 150,000 miles on the odometer. The cost should be around USD$90.00 + 1 Hour labor + Taxes.

If your car STILL hesitates, your transmission may be worn out. If this is the case, start saving your money and just deal with the hesitation until the transmission wears to near-failure. At that time, decide whether to replace the transmission or buy a new car. If you replace your transmission with a brand new one, it will cost approximately USD$2,700.00 for the parts + 11 Hours labor + Supplies + Taxes.

This is a fairly comprehensive list of possible solutions for your problem. I hope you find them helpful and that you simply need the software update.
