Thinking of purchasing this truck from a buddy he's the original owner - wondering with 153,000 KM 0r 96,000 Miles do you recommend changing the automatic transmission fluid as it was never done in 23 years??
Thanks for your time & response!
Might be all right if it's not too much money and a mechanic says it's OK. (Have it inspected before purchase.) How much longer do you expect to get out of a truck that's already 23 years old? Even with relatively low mileage there will be age-related issues to deal with. Pay particular attention to rust problems if you live in an area with salted winter roads.
A vehicle that old is most feasible to own if you do your own repairs. If you need to take the thing to a mechanic every time something goes wrong it could quickly nickel and dime you to death, and that's assuming no major problems.
