Buick Repair Questions? Ask a Mechanic for Answers ASAP
Do the cooling fan/s come on once it gets warm or hot?
Is the transmission fluid full?
Is the transmission fluid burnt smelling or looking?
What Diagrams, Manuals, or Instructions are you asking for?
I asked you a few questions in order to help diagnose this and am waiting on those answers.
Is the radiator boiling over?
How hot is it actually getting?
Do you have a coolant temperature gauge or is it just a warning light?
If the transmission is running too hot and the transmission cooler is inside the radiator then it could cause the engine to run hot and visa versa if the engine runs hot and the transmission cooler is inside the radiator then too the transmission cooler will get too hot and the transmission fluid could get hot and cause transmission problems.
