If I were to replace the solenoids first, what would the likely scenario be if your analysis is correct. In other words, might I buy us some time, or do the shift solenoids only mask the underlying problem. And, given that I've noticed no symptoms of slippage, is it possible that if we drive the car gently (e.g., 55 on the highway), we could get some continued use before tranny failure. Or is this too risky, in your opinion? I understand that there are no guarantees here, just trying to get more of a sense. (And--if I replace the solenoids and then go for the rebuild, would I have to get new solenoids again?). Thanks.
