Re: Shifting

I will check vacuum and if it tests out ok I will try adjusting the valve tonight and see how it goes tomorrow. If it still acts up I will replace the valve tomorrow. What else would cause this abrupt shift delay in the 1-2 and 2-3 shift? Stuart I really hope you are correct and it is only a vacuum or valve problem.

Other than a ruptured diaphragm (which I believe would be apparent if there was fluid in the vacuum line) how else can the modulator fail? I ask because I have no fluid in the line and the line itself is good. So Im puzzled...

BTW originally these cars had a metal line for vacuum but mine has all hose (about 3 feet). I made sure it wasn't cracked, but is it bad practice to have all hose? It is a thick hose and it does not collapse under vacuum but Im not sure if this is correct.
