1999 Subaru Legacy, 2.2L engine, automatic transmission, 124K miles.
I bought it just last month. I notice that the shifting at around 20-30 MPH lags about 40% of the time. (I think this is from 2nd in to 3rd?) I will be going 25 MPH and giving it more and more gas, and it just stays at 25... does not accelerate despite my gently advancing the throttle. (Meanwhile, everyone is justifiably tailgating me.) When this happens, the only solution seems to be flooring it, which (after 2-3 seconds) will force the revs up way high, and then it thankfully kicks in to the next gear and all is normal again from 30-35 MPH on up. Not exactly safe or good on fuel economy.
I am not a gear-head, so all I did was check the ATF level, which was full & seemed correct.
Is there a known issue with lagging shifting in the 99 Legacy? Anything I should be on the lookout for, or that I can check on myself? I can live with it if it's just "the way these trannys are", but if I am slowly killing the tranny, I'd like to know in order to be proactive. Thanks for any thoughts.
