The RPM's shoot up and I can't go any faster. It also makes 3 clicking noises when I try to accelerate. It never has done this before until we took it to autozone (last night). We had a check engine light (we just installed a new engine two days ago) and so he checked the codes on our car. The first time gave him a bunch of error codes, so he tries again and it gives him one code, which is P1780. I don't understand it was working fine until right after this happened after he reset he gave us the code we drive off and get out on the highway and can't go over 20. I disconnected the negative on the battery for 10 min and it still does it.
I really think its the ECM guys, the transmission is fine as far as I know it checked out fine when the engine was installed. It ran better than it did when we got it from the dealer UNTIL we took it to autozone and had it checked thats when all this happened.
