To start off with, 97 with automatic transmission.
This morning I changed the oil and filter and air filter and decided to clean up the motor. I sprayed it down with Simple Green and with the motor running rinsed it with a hose, not a deluge just a light spray to rinse off the motor. While doing this the motor kicked up i idle to about 1000 rpm. I drove the Jeep afterward and the Check Engine Light came on and noticed the shift pattern was odd.
I drove onto the freeway and while drive up the onramp the motor upshifted fairly quick and I reached cruising speed (65-70mph). When I stomp the throttle the Jeep won't downshift out of Overdrive or doen into 3rd gear. It just slowly gains speed.
I can manually downshift into 3rd and the power is there.
I disconnected the battery and let it sit 10-15 minutes. The CEL is off, but the problem remains.
Any ideas?
