Transmission problems please help
 

It shifts fine just driving short distance, occasionally rough shifts but overall good. Long distance on the other hand it shifts terribly for every gear, I mean like it will rev out then slam In gear. So my only guess is the transmission cooler is clogged? The fluid is still translucent and red, did a fluid and filter change when I got it, could add that I broke a cylinoid and had to replace it cause I was trying to not have to move the cross member, I don't know if that would affect anything . Any input at all would be helpful.

Have you checked the torque converter? Might be a possibility...

Anybody? Thought this forum was supposed to be helpful.

Thinking of how I could convert it to a manual has it been done? It's a 99 ls 2 Dr with 3 button 4x4.
And its just about at 200 k (199k) so I'm assuming it's worn anyhow. I don't know for sure though, any opinions? Rebuild/swap or is there something minor I can repair? I've done a filter and fluid change (5 quart not complete) with no luck, fluid is red as a cherry. On the interstate it will randomly down shifts Also.

This past summer I picked up a used Tranny from a junk yard for $300 bucks. The shop wanted $800 bucks to rebuild the 1 in it. I saved a ton of money :) It is doing fine to this day...

Okay thanks for your input, probably gonna buy a junk yard trans and rebuild it myself.

Fluid is fine and no clutches in the pan, has p1870 and a EVAP code that is intermeidiate.
