If I got the P1093 code did I limp the tranny or what happened because when this happened I was not able to go over 2000 rpm's. The engine did not sound any different it just wouldn't go over 2000...

do a search on P1093. You will get lots of reading.

No its not a tranny limp but rather a low fuel pressure condition.
