1997 626 transmission
 

Well my transmission has started slipping first to second is fine but second to third is slipping seems like Od is slipping aswell
The past owner of the car paid $2500 for a rebuild about 2 years ago
Id like to try and diagnose the problem
The Fluid is a pretty red so i dont think its been over heating any ideas are welcome thx :/
