Default new motor good, old trans bad..

Help ! I posted in transmission sections...but don't think that board gets the traffic this does.

Got the 355 running last night - very nice !!!! But the transmission (that was supposed to be good) doesn't shift into 3rd. First, second and reverse are fine - no third. Thoughts ? I was thinking maybe limp mode ?? (Hoping more like it) what does limp mode do ? It was probably in it when the motor spun the bearings and the guy drove it home rattling all the way. He did say something about it not shiftin into high or something - I was thinking limp back then. Anyhow - it would be the first thing I found on this car that the guy I bought it from lied about - but I did pull the pan off and change the filter and it looked good inside, clean - not burnt - nothing. It does have plenty of fluid.

I'm pretty sure the "limp home mode" would have reset if you disconnected the battery while doing the engine swap. I hope it's nothing serious.

That was my thought too...but maybe something else has put it back into limp mode....I removed all the emmissions from the car - and have SES light on - so the computer may be doing this. That's why I was wondering what exactly limp mode does ???

not sure what codes are throwing. Don't have a way to read them.
