I finally figured out the issue. Transmission is going out. Still runs fine I just can't force RPS to 6k or full send bc it stutters and struggles to change gear when RPS are past 5k. I am looking for a new transmission so I can do a swap then rebuild my current one so I always have a backup. I can not find the exact model transmission. Car Part Planet is saying my transmission is F4A4B1J1Z. Under my hood it states F4A4B that is all. Can someone help me confirm what transmission my car has? Also the best site to buy Remanufactured transmissions?
