Didn't see a recent thread, or any actual fixes for the issue in the archives so ill post up my issue here.

Car does this intermittantly...
Hard shifting with hesitation and jerking, also applies when accelerating from a coast.
The code reads as the TCC stuck open, and it appears that i am leaking fluid at a very very slow pace (mounts are moist, but thats it).;crap

I had the fluid changed at 63k but not flushed, and I am now at 87k. How much do you think this is gonna run me? I didn't see anyones results to the issue before in the TSB section.

Thanks in advance,

i told u what to look for, there are alot of TSBs about the range sensor, so i would def look there first, and a fluid and filter change and also flush the trans cooler, meaning take the lines off the trans and use the cooler flush to blast it out
