Hi,1993 xj6 VDP, while driving cold the transmission is kinda sluggish ,and the transmission warning light is on .once warmed up .,I turned the engine off ,restart and the transmission is perkier and the light is off ,I have not changed the filter yet ,the previous owner had it sit in the garage for 2 years .can anyone tell me where the vaccum trigger is and what is the solution to that problem .how do I check the function of this vaccum trigger
cheers marc
