gmefixit; Welcome to Hotrodders.com

I merged your two threads into one here.

What is the mileage on this trans?

There are several areas of the trans that can cause a code like this.

Valve body PWM circuit wear is common, Wear on the stator bushings and the converter lock up clutch material may be deteriorated causing excessive slippage the PCM is reading

:pimp:

I just had the trans rebuilt and it has 25,000 on the rebuilt rebuild

1860 is ignition feed circit most common ign switch failure 1870 is a internal trans issue

this info is incorrect. as crosley stated, it is for the tcc pwm.
here is a link to describe the code http://www.ls2.com/boggs/a4/DTC%20P1860%203.8.htm

thank you that is exactly what I was looking for. :boxing: :boxing: :cool: :cool: :cool: :cool: :cool: :cool:

I'm having the exact same issue with my 97 Camaro convertible (V6). I bought the TCC solenoid at Napa for about $8. Doesn't look to hard to fix. We'll see if that takes care of it.

gmefixit 08-31-2011 11:22 AM

thats cool let me know the only problem with mine is that it is inside the trany

imacarfan2 08-31-2011 11:50 AM

Mine is, too. I hear it's pretty easy to do, though. Drop the pan, pull one of the other solenoids to get to the TCC solenoid, disconnect the wiring to the TCC solenoid, replace it, then reverse this procedure. This isn't the exact procedure, but it gives you an idea.

You also have to check the wiring going to the TCC solenoid as well as I guess this can sometimes be the cause of the issue. Along with this, you can actually buy the solenoid one of two ways: with or without the wiring harness. Without was about $8, with was about $40. I guess the harness is pretty easy to replace as well.

Since you'd be dropping the tranny pan to do this, might as well buy some fluid and a filter kit and replace those while you're at it.

mine are on the end of the trany and I need to drop the K fram to do this so
I am also going to put new cluch plates in at the same time.

Crosley 08-31-2011 06:23 PM

I apologise , the code 1870 was in my mind since I see that code so often this year. p1860 is a more wide capture code of solenoid problems. Often the PCS is looked at for p1860, but the TCC solenoid can be at fault too, some trouble shooting will point to the pressure manifold.

Depending on mileage of the transmission, you may want to replace the soleniods and pressure manifold on the v-body.

Has the vehicle been turing on the warning lite for over heated transmission?
