Review on 🔌 ACDelco GM D2256C Park/Neutral Position & Back-Up Lamp Switch: Genuine Original Equipment for Reliable Performance by David Pullen

My transmission was showing numerous codes on my Allison transmission. went into limp mode and stayed in 3rd gear, shift light flashed and wouldn't come on in park, and rattled when going into reverse, sometimes wouldn't turn on at all before spending thousands of dollars on this part from Amazon it is a factory spare, and the GM stock is about 300.00 and it's not hard to replace. If you bring it to the store, it doesn't take 1 hour to exchange it. Got it and a new one in less than 30 minutes. thanks amazon
