Parts & Accessories Spare parts There is a 5.3 engine with a 5-speed manual transmission for a GMC, model 2004. The engine, God be praised, has no oil leaks, no overheating, and no noises, thank God. The oil pump was changed about two months ago, and the oil pressure is excellent, praise be to God, about three-quarters. The transmission is fine, shifting is good, but when shifting to fifth gear, there is a whine. The highest bid is 8500. Whoever is interested, please bid higher. The engine and transmission are installed on a 2004 GMC Suburban. It is working. Whoever wants to check it is welcome before buying.
