Scotty / An automatic transmission question Recently bought a 2006 Toyota Sienna LE w 110 K miles.
When I shift from PARK to REVERSE there’s a hard THUNK. But if I shift from PARK to DRIVE, then move and inch or two forward first, then shift into REVERSE, there is NO THUNK.
And occasionally when I’m driving and slow down and the car downshifts, there’s a hard thunk.
It also has a problem shifting from 2nd to 3rd… it slips just as it’s supposed to shift into 3rd. To remedy that, I pretend I’m driving a STANDARD ... and lift my foot off the accelerator just about the time it seems appropriate to shift into 3rd, wait a second till I feel the car shift and drop into 3rd, then I resume driving.
Are these two issues connected? Is there some sort of pressure plate that shifting into DRIVE first helps release? Do I need to rebuild the transmission or could it be a shift solenoid or speed sensor ?
Am I doing more harm to the tranny by driving it this way or can I continue driving this way until it completely fails then get it rebuilt...
