Tf 80Sc Software Make Sure

A shift flare followed by hard gear engagement while under heavy engine load can actually break internal components.

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.

It appeared on many Volvo models but only seems to be a consistent problem with ealier models (so far) 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.

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, its not due to lack of strength.

It is rare for these transmissions to have any sort of real mechanical damage or to actually be worn out.

I contacted various Volvo specialty and transmission shops in the Portland area and discussed issues they see with the TF80.

Most of the shops confirm that they rarely see a TF80 actually fail to the point of needed to be rebuilt.

Most of the problems with these transmissions can be solved without removing the transmission from the car.

Tf 80Sc Software Make Sure

If you are having shifting issues with your Volvo, your first steps should be: Use a Volvo VIDA station to make sure the Transmission Control Module has the latest Volvo software Make sure the transmission fluid is clean.

Flush if in doubt.

Probably should be done every 45,000 miles or less) The most common issues with these transmissions is Shift flare and hard downshifts.

Shift flare is a condition that occurs on up shifts between a lower gear and a higher gear.

The transmission will simply shift out of the lower gear and have a delay before engaging in the next higher gear.

This will result in the engine RPMs flaring (revving high) prior to the next gear engagement.

It seems to be more common with lower gears but can happen with any of the shifts.

Typically, the transmission will start exhibiting the symptom between the same two gears.

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.

Sometimes when applying the throttle after almost coming to a stop, you will get a harsh gear engagement but without significant engine RPM flare.

The most common shift flare is between 2 nd and 3 rd gear but the issue can occur between any gears.

The flare may not occur consistently but will be between the same two gears.

In other words, you may intermittently get a flare but it will always be between 2 nd and 3 rd.

I have yet to see a transmission that has flare between multiple gears but it is certainly possible.
