I looked at one to today with the workhorse 7.4, will that unit have a "Allison" 4 speed or is the the standard GM 4 speed? The owner thought it was an Allison but I'm not sure. </div></BLOCKQUOTE>Well this is a bit confusing but "IF" the Flair has a 7.4L it definitely has a GM 4 Speed. Now if the owner is correct and says that the Flair has an Allison then the motorhome has an 8.1L engine.
Check the 8th digit in the VIN#. A "G" is the 8.1L engine and a "J" is the 7.4L engine.
Most likely the tranny is a GM 4L80E.
