Gearbox behavings
Discussion
Some strange goings on with auto gearbox in xc90. 5 speed aw55 Aisin Warner. Gearbox is as smooth as you like all gear changes are perfect however torque lockup isn’t engaging as it should.
It always engages above 55mph and behaves perfectly. It won’t engage during acceleration in any gear. So it’s slipping but that’s normal when torque lockup isn’t 100%.
I’ve changed the oil and it’s cherry red now as it should be. But that didn’t change anything as I said above it’s driving perfect it just won’t lock up before 55 -58 mph ish.
Need the car in the summer for a long road trip around Spain with a wife 4 kids and a bootful of gear so need to make sure it’s as good as can be before we set off. Zero codes as checked on Vida.
