Re: P1870 Code

so my torque converter isn't locking up making the rpms run high?

That is what seems to be the most common issue, but it is impossible to tell over the internet.

I'm going to give the $22 part a try - What have I got to lose?

Re: P1870 Code

I ordered the part yesterday. How long do you think it will take to get here? I've never dealt with the company before.

FOLLOW UP -

I had the hard shift problem from 1-2, especially after the car had been driving for a while (ie, warmed up). The car eventually gave a code P1870.

I ordered the $22 Code P1870 fix part. It is a replacement valve. I paid a mechanic to install it.

Four months later - the problem has never returned again.

I highly recommend giving this a try for anyone getting hard 1-2 shifts and/or code
P1870.

As a matter of background, this occurred when my car was in the ~167,000 mileage range.

Re: P1870 Code

so that valve stopped the 1870 code and it also stopped that 1-2 hard upshift??

It absolutely fixed the problem for me. I thought my tranny was dying before and now everything is back to normal.
