Given your proximity to johnhef
, that sure sounds like the way to go.
I had really bad slippage in the SEC, mainly from 2nd to 3rd. I happened to take it to a closer Indy I'd discovered for some minor work & had him drive it to drop me off at the nearest watering hole
But, only after 1st warning him not to pull in front of oncoming traffic too fast.
When I got the car back, viola' - the slipping was gone! He later said 2 wires had been disconnected, 1 causing it to always think it was in kickdown mode, no details about the other wire, just said it looked like someone was 'screwing' with me or the PO!
He told me he also adjusted back to factory spec (bowden cable? or modulator) took it for a spin, brought it back & adjusted some more. Invoice was $120 just for the work I'd expected, but when I drove home - all I could say was WOW! Later he told me he knew I'd be happy with the results - radical understatement.
Tranny up-shifts sooner than accustomed to, and will still shift hard
engaging reverse - once the car gets hot. So I realize the thing IS on it's last-legs, with no way of telling how much time he managed to buy me. But this guy sure knows how to build customer loyalty
