4eat and rpms in 4th

[98obster]

okay, granted, it's been cold lately so that may be a cause but I'm wondering if this is a sign the tranny is in its twilight or maybe a sensor.

 

the 98 4eat shifts fine and gets up to speed okay but lately it sits at around 2800 at around 60mph and a couple miles or so the tach will settle back down to its normal 2500 rpm. it's definitely in 4th when this happens and not 3rd finally going into 4th. Any ideas?

This cound be the emission feature on Subies. I notice it more on the 2.2 than the 2.5, but the transmission will wait until it hits a certain temp in cold weather before allowing the toque converter to lock up, forcing the engine revs higher for a faster warm up to operation temperature.

 

If if behaves correctly in warmer weather or when it's started again after a slight cool down then this is most likely what you're experiencing.

ooh, I hope that isn't the same as toque de muerte that I hear about

 

anyway, i hope that' it. the rpms will actually decrease when I'm going up hill. damn, I thought my 4eat had suddenly evolved into a 5eat. thanks.

Torque converter = good (required part of 99% of automatic transmissions)

 

Torque bind = bad (result of toasted piece of subaru AWD transmissions)
