Buying a truck - Transmission fluid flush time?

[Wenchonahorse]

I'm in the process of buying an '04 F350 with 190k miles on it. I'm trying to find out the most recent time the transmission and coolant fluids were changed, and if I should have them do it before I buy. What's the milage interval I should be looking for for either? I have been told (and it feels like) the truck has had very regular service, and the last 90k miles were highway non-hauling.

if they change the coolant your gonna be doing a oil cooler. bring some sort of monitoring system with you to check over all the engine temps once you have had it running for a while. check after driving for loss of coolant, rough running truck, white smoke in the tail pipe, any sort of start that you consider long is always something to look for too. and when you get it up to temps shut it down for a minute and make sure it restarts... hopefully someone will give you a link to the 6.0 buyers guide. tons of good info to look for in that thing. and take it by a ford dealer and get an oasis report.

I totally agree with the above^^^. If you buy a 6.0 with out running a monitor on it your buying it blind. The truck could be good to go, nothing needed but fuel. And then again it could be a rolling time bomb. $150 monitor and "now you know the rest of the story"
As far as service on the truck, mine had 101k miles on it and I took on the truck with the feeling that only the bear minimum maintenance was done. So as time/money permits I will change out every last drop of fluid and try to go synthetic. Change every filter. I have changed belts/hoses. And upgrade anything needed. I figure Ive got $25k in the truck. But I couldnt touch a replacement new truck for twice++ that.

The trans service is easy. Order your filters and oil from dieselfiltersonline.com. They are the cheapest. I think the book said the trans should be serviced every 30k. But I don't remember for sure. There is a good video on YouTube about how to service the trans. I have a buddy that's been looking for a used diesel. I have been going with him to look at trucks, and I didn't realize how lucky I was when I bought mine. There is a lot of junk floating around out there.

Thanks guys! Everything seems to check out on the service records, so it came home last night ^.^
