I have seen them all, dyno tuners setting the car up to never get 100% throttle in an attempt to smooth out gearshifts(WHY?) along with cars that would hold gears until next week before shifting. A dyno is not the place for setting up an auto to shift correctly, it takes months of data analysis on the street to improve gearshifts and even the same make/model often require tweaking of 100rpm or so between cars to optimise the shifts to suit a specific gearbox wear/age/fluid etc.

The transmission control unit is not programmable but it does not need to be, feed it the right signals from the ECU and it shifts perfectly fine ;)

Yeah, 100+ inquiries from the US Legacy owners in 6 weeks after a video went viral! Some of them are Workshops wanting my tunes(atleast they are honest) so they can reverse engineer them as they have spent 8 years trying to get it right with little success.

Imitation is the best form of flattery? :lol:

I dont think its anything my tuner has done thats causing gears to hold (in auto). I reckon its just the subaru factory settings. I almost never drive my car in auto anymore because I get too frustrated with the gear changes/slips/over revs.

How harmful is the over revving and slip on the auto box?

With a downpipe and tune it feels like the autobox cant keep up anymore.

I had a similarish problem when i first brought my car. BUUUUUT it wasn't with the transmission. I noticed a stutter just before boost came on but once i got my car tuned it fixed the problem straight away.

FYI Car is a manual and was completely stock before the tune.
