Thread: cat. can cause shift problems.

Hello to all,I am posting this to maybe help others. I have a 01 GTP and have searched and searched for help with the shifting problems. Mine would not shift properly on its own and if I shift it manually,it would run better. I had the codes run on the trans. and the exhaust.The trans, was fine,the catyletic converter showed 70 percent collapsed. This pushs burt emmisions back into the engine causing it to spudder. The PCM then comensates for odd shifting in the trans. Replace,remove or have the cat. checked. I hope this helps with your ride,it did mine. Thank you.

ehh I dont let my cat touch my car anymore... last time I let him swap out my valve springs and he got hairballs in the cylinder and his claws effed up my paint. If he messed up the tranny that would be the end of him...

jk I've been havin some minor shifting oddities lately with no codes, I'll chime in when I get my new downpipe and cat in the next month or so and see if it improved conditions.
