When rebuilding your transmission it is always recommended that you change the torque converter. Another method is to simply remove the valve and inspect the spring. How long is this code in your system for? It's been working perfect ever since. After repairs are completed, and for preventive maintenance, it may be a good idea to add an inline filter to the transmission cooling lines. If you have continuity between the fuse and the ignition switch, the most likely cause is the ignition switch. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely.
P1870 code on vehicles with electronically controlled automatic transmissions, the 3-4 shift solenoid is responsible for actuating the hydraulic circuits to activate clutches or bands that change gears inside the automatic transmission. At that mileage I would recommend a rebuild. Your computer has sensed a component slipping in your transmission. Driving a bolt into the converter cover will create a dimple on the lockup apply surface. I had a local shop check it out today. It seemed to slip or shift gears slightly back and forth.
If only the actuator feed limit valve has bore wear problems, Transgo 626-443-7456 offers a dedicated reamer and valve kit. Description: 4 speed rear wheel drive, electronically controlled, automatic overdrive transmission with a torque converter clutch. Easy fix by removing the pan. Fluid pumped out through the vent tube Plugged cooler line. This was the cheapest price out of about 7 estimates.
The car is safe to drive in 2nd until you can get it fixed. Remember, the code is set after the vehicle is in high gear with the converter clutch applied. On the older version of this trans. For the most part, all of these diagnostic strategies remain effective today. I also checked the fuse block in the engine compartment and the interior fuse block.
Fortunately, time has shown that in most cases it can be traced to some form of converter clutch failure—in particular, bore wear. The unit typically mounts in front of the radiator. The driver will have Reverse and 3rd, with manual 2nd available by putting the gearshift in 2 or 1 doesn't matter. Transmissionmission does not shift automatically, only manually. If you supply the parts and ask for warranty in the end you will save money.
This is the command that applies the torque converter clutch. This required a change in the pump assembly and valve body to accommodate the required hydraulics. You get kicked in the A everytime if shifts from 1st to 2nd? Your trans is called a 4L60E.

In addition to these changes in material, the tension of the damper plate springs, which are integral to the clutch disc, was also altered. Cause The most likely cause of this condition may be a loss of voltage to the transmission solenoid power supply circuit.
Don't really know how to fix it other than don't use the Cruise. New design one piece 3-4 Apply Plate. If battery voltage is not present at the fuse, test for continuity between the fuse and the ignition switch. Cheaper to rebuild now saves further damage to hard parts. . But just for gigles check that the transmiion mounts are ok and the mid ship bearing is ok and u-jints. I get a P1870 Code.
