I have an 03 TB 4x4. The transmission always shifts slow. Problems occures at all speeds, all operating temps. Fluid is full and is in good condition. TB has about 80,000mi on it. Any suggestions?

I had issues with the TB not shifting when flooring it. The TB didn't feel right, after about 13 miles on a dirt road the filter was dirty as can be. I cleaned the filter and she shifted normal again. I never did get and Check engine lights or codes either.
