Problem with my 1998 Chevy Tahoe
Mileage = 160,021
Engine size = 350
dash lights = yes
codes = p1870
work done prior = none
work done to repair = Checked the code "trans slipping"
checked fluid, full, and clean (red)
I believe the fluid psi solenoid is bad.
tech = any
question = normaly the vehicle runs fine..
then when put under a load or driven hard (highway), the light comes on
and the trans shifts funny.
When the trans acts up, the 1-2 shift is very harsh, and a burning
smell is present.
Upon sitting parked for around 1 hour, the trans is fine until you
apply torque to it again.
I will be changing the filter tomorow, but would like your opinion.
SF:
P1870-component splipping, can be caused by a problem in the valve
body, but with that many miles on it, it may just be time to overhaul because
of slipping components, The condition of the fluid-if burnt, means trans.
needs to come apart and look for a failure. Again, with that many miles,
probably just worn out. Try the filter and fluid change to see if it helps. The
hard shifts are most likely caused by the line pressure being raised to
compensate for a slipping component.
