Wasn't sure if there are any auto mechanics lurking about but I am frustrated.
I had the engine replaced in my car this week.
Picked it up yesterday and the mechanic said the tach is running high. When you are on the highway, it sounds like it needs another gear to shift into. RPM is running at the 4X level versus the normal 2X.
Any idea how to fix this? If my mechanic is shrugging his shoulders, I am concerned!

Thanks in advance,

I don't know but I would take it straight back to him and if he can't fix it get your money back and take it to someone who can fix it. I wish I had a better answer for you.

Not a mechanic, but it sounds like a mismatch between the transmission and engine. I'd definitely get a real mechanics opinion.

Correct - he is the one that told me when he took it out on the highway it is tach'ing high....that it sounds like it needs another gear to shift into. He is the one that said it is tach'ing at 4x but he would like to see it at 2x.
He is actually a reputable mechanic who has been doing this for years. Therefore, he would of made all the adjustments he could think of. THUS is why I am perplexed.
Guess my other question is....anyone out there have their engine replaced and it runs like it did before? Or when you replace one, should you expect quirks?
I assumed it would be like it was before.

Possible clutch slippage, oil on the clutch plate, weak pressure plate, clutch plate installed backwards, clutch linkage too tight etc.

TR - When I went to pick up the car, he told me the clutch was wore down to the pin so he did put an entire new clutch kit on.

Clutch is installed wrong, slipping.

Uh yah not a mechanic, have done my fair share of engine work, before cars were computers though.
This is unacceptable. I would take it back to him and tell him it's not "fixed" and until it is "fixed" you will be requesting a loaner car. If he can't 'figure' it out he needs to take it to someone who can.
Seriously. You have to be a hardass with these guys sometimes. You probably won't get the loaner, but you will get your car fixed. If not threaten to call whatever TV station in town does the reporting on shotty buisnesses. 
You have been willing to pay, but you expect to have a running vehicle.
Oh and it does sound like a clutch issue.

If your car is a manual transmission, it doesn't make sense that the engine would now be turning at a higher rpm in top gear. Are you sure the rpm is fine and it's not just the tach?
HereWeGo62 ( member #34766) posted at 3:59 PM on Monday, August 26th, 2013
I agree with the posters above that there is an issue with the clutch or pressure plate. Engine RPM at a given speed is derived from the final gear ratio of the transmission and final drive gears. If nothing was done to either of those two things and the engine is a direct replacement than it has to be the clutch or pressure plate.
The clutch disk is a friction plate that connects your engine to your transmission, if it slips your engine rpm will rise. Have the mechanic re-check his work, the extra RPM's will kill your gas milage and eventually other mechanical pieces in your car.

It's been a week - the curious mechanically-minded want to know what it was.

Update: IDK
Sighhhhh
I took it out the other night and it was running just fine (RPM wise) but then my DS started it the next day and it was revving high (just while idling)....but then it went back to normal in a few moments.
I noticed it sounds like the valves are knocking sometimes (going up big hills or it you are REALLY accelerating). Took it back yesterday and the mechanic only found a lose hose. He put it on the machine and said it showed no codes and was running fine.
So it seems the high RPMs in 5th gear is better but now it is knocking a little.
This whole thing is frustrating as heck.
Will minor knocking valves hurt a darn thing?
