ACDelco GM Original Equipment 24215111 Automatic Transmission Manual Valve Position Pressure Switch

All Ok 😁

Works on my Chevy 1500 1997. Fixed my transmission.

Fit like OEM. I would be careful with the torque. 2 different size bolts to hold it in place. It needs to be tight cause of fluid pressure. I had 1 bolt I thought was gonna strip but all in all it’s working perfect.

Genuine ACDelco part, worked perfect for my 4L60E transmission at half the price shops in town wanted to charge me.

I had bought a remanufactured transmission, and it went about 1000 miles and started throwing codes, shift solenoid codes and this part. At first it was just shift solenoid codes, P0751 and P0753, then when I was ready to drop the pan and replace them I checked for codes and P1810 popped up as well. I decided to order the part before dropping the pan for the shift solenoid valves. I checked line pressures first; they were in range. Then I dropped the pan, replaced both of the shift solenoid valves and the TFP switch, also replaced the filter with an AC Delco filter, all parts were AC Delco, I have a feeling the rebuilder was using aftermarket parts, not OEM, the filter was plastic, the AC Delco on is metal with a plastic neck. Just because the pan gaskets always eventually leak, I installed a Moroso reusable gasket, a little spendy, but they never leak. The rebuilt transmission always had a hard shift in pretty much all gears. Before repairs I was experiencing second gear starts and slippage in Overdrive (4th gear). I cleaned up the pan, minimal material on the magnet, normal clutch dust, no metal or brass. Filled it up with synthetic ATF, all I ever use. Cleared the fault codes, then started it up, let it get the fluid going through it, then went through the gears, let it get warmed up, topped off fluid, took about 5.5 quarts total. Took it for a test drive with a scan tool and watched operation of things, gear commanded, TCC lock up, etc. Shifted like butter, no more harsh shift, no returning codes, hitting on all cylinders. Downshift great, no slippage in Overdrive. Problem solved!! Going on a 3500 mile road trip in a couple of weeks, so I am glad this worked out or would have had to cancel. OEM parts make all the difference, worth it, and these were cheap enough. This is an easy enough repair for someone that has moderate mechanic experience. Most people get intimidated working on automatic transmissions, if you are just working on the bottom end of it, it's really not that bad. It helps if you have a scan tool, that is for certain.
