I have 68K on my '96. I started to have transmission problems at 1k (Yup, that's 1,000 miles) The transmission was replaced by the dealer at 10k and then upgraded around 35k.
Check the condition of the fluid - pink, not brown or burnt. TC engagement should be reasonably firm somewhere around 50mph. All other shifts on a stock transmission will probably feel mushy, i. e. like one of those constant velocity transmissions; or a single speed go cart...
