i bought a car with a new engine and it runs really good but the transmission doesnt shift good unless u take your foot off the gas and then let it shift like a manual. and to me it looks like its been a swap from a manual to automatic because theres a whole where the clutch use to b and worn carpet in the same spot. also it looks like all the stuff under the hood was mounted for a manual like the master cylinder. would my car shift bad because it is a automatic with a manual ecu or would it not know how to shift because of the ecu being for a manual

ECU for an automatic and for a manual transmission are not interchangeable.Not only that,wiring harness under the hood are also different,automatic transmission has more wiring for shift solenoids and torque converter clutch solenoid,when manual transmission only has wiring for the back up light switch.Check your harness and part numbers on the ECU.
