LIM changed out by mechanic, now tranny is shifting HARD

[jerrad]

Just had my lim done by an engine shop. never had any previous tranny problems very smooth. Now when i get the vehicle back after 15min of driving the SES light came on and the tranny jumps really hard before shifting....What did this guy mess up?? any ideas??

I had a similar issue, but I cant guarantee it is the same issue because I'am not a mechanic. But I forgot to put the end to my IAT sensor back on when I installed my new air filter and it shifted exactly like you said. But as you said he was working on your engine...so I'm not sure why he would mess with this piece. You can hope this is the problem though because it costs nothing to fix. Sorry but I'm not too sure ... :???::???:

check you maf sensor connections

[jerrad]

would he have disconeccted those to get to the LIM?

Most likely, yes.
