When was the last Transmission service completed ??
Colour, smell and fluid level ??
I have repeatedly asked, the OP will not divulge, seems he is waiting for the silver bullet...Have you started to diagnose yet ??
Condition ?? Have you checked the shift down cable adjustment ??
The fluid level is good, fluid pressure test first I'm hearing about that,shift leakage set at I really don't know I have to ask the transmission guy.BUNGLES, You are aware that we are no standing beside you and can only help if we get ALL the information..
We have had to drag what little you divulge bit by bit...
What is the fluid level (HOT), and what is the shift linkage set at, have you considered a fluid pressure test ??
