Whats up guys i have a 2006 dodge ram megacab 1500 5.7 hemi No MDS it through a rod broke the aluminum oil pan it has so I called a few wrecking yards and one place had the engine. I drove 2 hours to go get it. I replaced the oil pump water pump rear main seal and
Front seal had to use my old mounts because the ones the engine came with are different i installed the engine went under the truck to make sure everything lined up and I noticed the bottom half of my transmission has nothing to bolt up to so i'm assuming I was sold the wrong engine also oil filter is damn near touching the frame and exhaust manifold damn near touching i'd appreciate any help you guys have

Update...So i found out the engine that was in my truck is a charger engine i tried installing the correct engine from another 06 mega cab but the stock engine mounts it didn't let the engine sit correctly so i put the mount that were used for the charger engine on the mega cab engine and the oil filter was touching the frame and there's nothing to bolt up to the lower part of the engine to the trans with the metal oil pan vs the aluminum oil pan i had before my trans says 434 RFE any idea what engine would be right for my trans and engine mounts

First off make sure the oil pan matches the one off your old engine it needs to look the same if its not order a new one and swap it out. AS for the bottom half of the transmission your missing the bracket that bolts there once the converter bolts are in,. What did they say the engine came out of? It looks like you may have a motor mount issue are you sure you put them into the correct bolt holes on the block? its for sure sitting low.

look under the intake manifold you will see MDS solenoids if it has MDS if thats the case yes wrong engine. Also next time nerver give up your old engine until the new one is installed you never know what you need ahaha.
