Please explain "Strange Shifting when cold" a bit. I've been having (for a few years) a situation as follows "and" only when the temps dip below the mid-50s and only until trans temp gauge bumps off the low reading of 100 degrees: in drive, head down the road normally, quick shift into 2nd, then 3rd and then boing into OD, then as you come to a stop or slow down it acts like a std trans that you forgot to downshift - I'll put in "N" and then upon stopping back in "D" and off she goes....My first clue was strange shifting when cold.
Sorry to hijack post a bit. Love my DTT with 15 years and 100k+ miles on it.
