The first thing we need is for you to get codes read, at autozone advance o'reilly's etc
Then come back with the actual codes, NOT what someone thinks they mean.
Codes start with a letter then four digits.

Did you happen to do any work underneath the car recently.. or go off-road through brush or anything?

Crawl under and look for wiring coming anywhere near the exhaust.

Meantime pull the ABS and cruise control fuses.

 

I checked wiring could not find and thing bad ill try the fuses thanks

 

You know a clogged up cat can feel alot like transmission problems if it will shift into first under pressure its most likely not the tranny.

 

Ok thanks ill check it out i dont think my trany is bad it just started out of on were never any probs out of trany before
