So I am pretty sure that my trans is finally giving out on me. The trans shifts firmly from first to second, then intermitantly, and sometimes refuses to, shift into "drive." This problem came about a few days ago. I think the flogging I gave it a few weeks ago didn't help matters much Anyways, I drained the trans fluid and it wasn't burned up, replaced the fluid and filter and the problem is still around. With that being said, is there anything that I can do for a reasonable cost to save my 260000 mile trans, or should I just rebuild or purchase a new one? Opinions and options are greatly appreciated.
