MANUALLY SHIFTING YOUR AUTO IS FINE
I love it how people always just blame their auto tranny failure on manual shifting, when more often than not that had absolutely nothing to do with it.
More than a few Accord V6 owners kept on saying that manual shifting caused their tranny to fail and I said it wasn't so and they didn't believe me. Now Honda just extended the warranty on a lot of their V6 tranny's to 7yr/100k miles because of a DEFECT in the transmissions that might cause them to fail prematurely.
Yup, it was that manual shifting all along :chuckles:
Like Mr Hyde said, the tranny is going to be shifting regardless. What difference does it make if YOU decide when to shift instead of the computer? Even then, there is plenty of idiot proofing built into the PCM (Powertrain Control Module) to prevent you from doing stupid things...like downshifting to 1st at 60 mph
