My buddies trans behind a 95 6.5L is locking itself in 2nd gear when it warms up.

Anybody has any ideas what is going on?

Tranny and coolers just got flushed and the tranny has approximatly 350k km's

I always stay away from servicing units with high miles like that. Especially if it has never been done before or not done in a long time. Most times you open up a can of worms. I just had a customer call me today with a Rodeo with high mileage and I told him I would rather not service it.
Has he had a scanner on it, any codes>???
