1996 cadillac seville. When car is cold, it turns over and drives fine. After a few miles, the transmission heats up and begins slipping. I have to turn it off and let it cool before I can drive it any more. I dont think and gears are burned up cuz I makes it into 6th gear fine, it isnt until it gets heated from friction that it starts slipping. I think the transmission cooler might be bad, and if I replace the trans cooler, it will have the transmission functioning normally again. The radiator was cracked before and I replaced the radiator. Also I just recently replaced a leaking water pump

If it is slipping, there is a high probability that the clutches are burned. You do not have a 6 speed transmission, It is 4 speeds with torque converter clutch. My guess is you have an internal concern, and replacing the transmission cooler will probably provide no correction. Is there a check engine light occurring, when the fault symptom is present?

Yeah it has the check engine light on all the time. I took it to a shop a week ago and they replaced a leaking water pump, I think they ran it for codes. I have a 50k mile, 3 year GM transmission warranty and it was replaced 2 years ago. I know there has been less than 50k miles since the replacement was done. Is this kind of thing covered under the warranty. I dont want to take it to the dealer and they give me some reason for why they dont want to honor the manufacturer warranty. What kind of things do I need to look out for?

If it is deemed a transmission fault, it should be covered under the parts warranty. What can help alot, is service records, and a good repoire with the dealer. If I am not mistaken, the parts warranty is 3yr/36k miles. If you have literature that states otherwise, I am incorrect. I would be curious to know the code(s), and I could let you know if they pertain to a possible transmission fault. Without having my hands on the vehicle to verify a condition, I would say if it is slipping, it should be covered.
