Alright guys hoping to see if someone out there can help me out with my 1993 astro van I've had hardshifting 1-2 since July of this year. I already changed the 1-2 solenoid, the accumulator is aluminum and put in a new spring. I also changed the TPS. Is there anything else that can cause the hard shifting? I've changed the tranny oil twice and it does have a new filter.
