Hard down shifts are basically the same problem in reverse. Early on, this may only happen randomly once in a while when the transmission is warmed up but as it gets worse, it may happen more consistently at any temperature. Typically, the transmission will start exhibiting the symptom between the same two gears. It seems to be more common with lower gears but can happen with any of the shifts. This will result in the engine RPMs “flaring” (revving high) prior to the next gear engagement. The transmission will simply shift out of the lower gear and have a delay before engaging in the next higher gear. Shift flare is a condition that occurs on up shifts between a lower gear and a higher gear. The most common issues with these transmissions is “Shift flare” and hard downshifts. (Probably should be done every 45,000 miles or less)

Use a Volvo VIDA station to make sure the Transmission Control Module has the latest Volvo software.If you are having shifting issues with your Volvo, your first steps should be: Most of the problems with these transmissions can be solved without removing the transmission from the car. Most of the shops confirm that they rarely see a TF80 actually fail to the point of needed to be rebuilt. I contacted various Volvo specialty and transmission shops in the Portland area and discussed issues they see with the TF80. It is rare for these transmissions to have any sort of real mechanical damage or to actually be worn out. Many people on forums were complaining that the TF80 is not strong enough for the V8 equipped models and “Volvo should have known better.” While it is true that these transmissions do have plenty of problems, it’s not due to lack of strength. Variations of this transmission are used by a lot of different car manufacturers, but Volvo seems to have more problems with it than other manufacturers. It appeared on many Volvo models but only seems to be a consistent problem with ealier models (so far?) The TF80 is a 6 speed automatic transmission manufactured by Aisin Warner. I found lots of people on forums having issues with the transmissions in these cars but the opinions on the problem and solution were varied. Soon after buying it, I started having transmission shift flare issues which ultimately led me on a quest for knowledge. You can find many repair kits that are used in any sort of failures of the AT.This article was originally written in relation to the AW TF-80SC transmission but this same information applies to the TF-81SC, AF33, AWF21, AW55-50SN, AW50-51SN & AW55-50LE transmissions.Ī few months ago, I bought a very nice 2007 XC90 V8 Sport. After a prolonged usage there can be problems in the hydraulic unit that forces you to have expensive repairs of the automatic transmission AW TF-80SC. This way friction problems occur and soon there are unpleasant jerks when shifting gears. Transmission TF-80SC problems does not handle aggressive driving. While other transmissions broke down quite often. A separate powertrain option could work without giving the owner any trouble for decades. This modification of the gear box turned out to be rather ambiguous. As a result, the frictions would break, and an expensive repair of the AT AW TF-80SC needed to be done.

Quite often drivers when manoeuvring in reverse try to switch the Reverse to the Drive without waiting for complete stop. A common cause of damage is the change of regime in a gear box in a moving vehicle. So, the car owner must be careful when changing speed and modes of the transmission. Transmission AW TF-80SC / 81SC has a complex structure and fully operated by the automatic system, this was the only mechanical connection with the gearbox selector. But a new improved transmission appeared, which could be installed on cars with an engine volume up to 4 litres. This modification was intended for vehicles with a working volume of 2.2 litres.
