Shiftpoints with cold engine V70-XC70 1998

posted by  someone claiming to be Andy on  Tue Nov 21 10:18 CST 2000 [RELATED]

My 98 V70 (turbo) automatic has always shown the following pattern: When the engine is cold, upshifts occur at higher RPMs than when the engine is at normal operating temperature. For example, even using very light throttle, shift from 1st to 2nd usually takes place after seeing 3-3.5K in 1st. If the person does not use light throttle, it reaches 4K easily in 1st gear. This is particularly noticeable after start up in freezing conditions.

Questions:

1) Does anybody else experience this pattern ?

2) Do you think this is an intended design pattern programmed by Volvo ? If so, why force the engine to go to higher RPMs precisely when engine wear is happening at the highest rate ? What is the logic ?

3) If this is not an intended "programming" of the gearbox by Volvo, could this simply be caused by the ATF being thicker when cold and this in turn making upshifts occur at higher RPMs ?

Thanks,

Andy
