This is news ... So there is a latest flash again, there should be a new TSB# or software ver#.
I had the early version installed, I think, and not very happy with it. I have the slipping clutch (car hops a few times when the clutch slips) mostly when taking off from a stop about half way thru 1st gear. This problem became noticeable around 20000mi and 2500mi after I got the 12B37 done. Could be coincidence, I need to have it looked at and check for the leak at the bellhousing.
Anyone that has access to info about the later 12B37 update please post! Thx!
