P1810 Code / Occasional Hard Shift
I had a P1810 code show up, (P1810 Transmission Fluid Pressure (TFP) Position Switch Circuit TCM)
I read a little about it, and I don't know much about cars, so I hope to get some info before having a mechanic tell me something beyond the real problem.
I noticed a harder shifting occasionally (but I read about this online). curious though, would this problem be associated along with this issue i'm having. when I press the break, the lock disengages in the automatic shifter to allow it to move out of park. Normally in drive, when you press the brake, there is no clicking/disengaging sound coming from the shifter. but after driving a bit, i start to hear the click every time i press the brake... this is when I know that the car will shift into the first 2 gears very firm.
are these 2 things associated? I'm hoping so, and it's just a 1 item fix.
thanks for any info. sorry I know very little about cars. but i'd rather tell you that than the mechanic!
2006 Cobalt 2.2 automatic.
