Exclamation Engine Swap/Clutch alignment?

Hey everyone I just had a 4.0 stock to ATK 4.0 swap done. Right out of the shop 1st and 2nd gear were hard to push into, and it grind whenever i try to put it into reverse. The jeep runs strong once its in gear it's just getting it passed 1st and 2nd that seem to be rough. 3-5 go in smoothly, maybe a little too smoothly....
anyways, i didnt know if there was something that misaligned whenputting the new engine in. Theyre trying to tell me its syncros or that my clutch is going bad, but it worked fine before the new engine. I just won't believe that it worked fine before the shop and then is failing due to natural causes after the shop. They used the same motor mounts, and it is the original clutch and tranny. Any thought? Thanks in advance.

Sounds like the clutch isn't fully disengaging. They need to fix it.

Thats what i thought at first, two questions.

1. is that something they just didnt align right when they swapped the engine out?
aand 2. if it was the clutch, shouldn't it affect all the gears?

pardon my naivety

I think the answers are in your other thread:

Hard shifting after engine replacement?

The lower gears always do not mesh as easily as the higher gears so it is natural that you would be having more issues with reverse, 1st and 2nd if your clutch was not fully disengaged. I agree with jeepwayoflife....you need to take it back and have them make it right.

no one was addressing the alignment question i asked, so I made another thread just on the alignment of the clutch and engine.

3 and 4 and 5 can be shifted into easily even without pushing in the clutch if you rev match. You need to go back to your other thread.

I'll answer. If your transmissionis bolted to your engine and torqued properly, your clutch is aligned. However, if the transmission input shaft is forced through the clutch disk hub, the clutch disk could be damaged or bent but that is unlikely. Possible but unlikely.
