HELP possible trans problems

hi i was wondering if someone could help me i have a 700R4 with about 135xxx miles on it also go a shift kit inside. when i gas it it feels like theres a lag going into first gear and its not as snappy as it used to be. also when i start it up it surges a lot from like 500 rpms-1500 rpms. anybody have any idea of what could be wrong? could the trans be going on me?

It sounds more like you need a tuneup, unless the engine is revving and the car isn't moving...

If its surging at idle then I would suspect something is up with the engine. When this happens at low RPM's are you in gear or does it also happen when you're in park/neutral? No SES light right?
