At a stop, I have to rev my engine either in neutral and shift into drive to get the tranny to engage, or rev it in drive and try to let off the gas before it slams into 1st. Then it misses the shift into
2nd until I either do the reving thing again, or wait about 4 seconds for it to shift on its own. I had a tranny shop replace the modulator, and that helped for an hour (apparently there was some fluid in the vacuum line). I know I have a crack in some hose in the top of my gas tank for two reasons....one, it will not pass the emissions vacuum test, and two, the one time I topped off my tank leaked from what appeared to be above the tank for a cupful. So, I am wondering, if not having proper vacuum in the gas tank can be causing my transmission vacuum problem, and possibly slight performance problems. The problem has gotten slowly worse, but I do not drive much. If I drive for half hour the shifting problem sometimes goes away. Advice?- posted
