I need some help, I have been replacing my auto transmission on my 2006 chevy aveo LS with my brother, we were able to get the transmission out no problem getting the new one in has been some what of a problem. We had installed the converter on first then jacked the transmission up in and got it inside the spline. But it doesnt seem to fit just right, it doesnt seem to be mating just right we get it up close to the engine enough to get the bolts in but when we start to tighten them we cant get the trans and the engine to be flush it has a few mm of gap between them. Something is just not right, are we not in the actual spline inserts, thats the only thing i could think that it could be. Please if anyone could help it would really help me out, spent all day today trying this and that to get it.
