Here's my situation--
'95 xe-v6 auto. ~180K miles. About a month back, got the timing belt changed, I'm assuming the water pump got changed as well, replaced something to stop oil leakage (head gaskets? I'm not too sure), and had an additive put in the transmission fluid to make her shift quicker (R to D used to take 2 to 3 seconds). Ever since then, all of the gear ratios seem to have become shorter--the tach reads about 100-200 rpm higher than what it used to be (ex: 60mph used to be @ 2400 in final, now it's about 2600). Everything runs fine, just at a higher rpm than before--same mileage and what not, too. I was just wondering if this was any cause to be concerned?
Alohas,
