Have a 2002 Excursion, torque converter going out, 370K miles on 7.3 L, transmission still shifts well. Excursion still looks like new, always garage kept. will put money in this truck rather than new. question is with the miles on this truck thinking about changing out transmission as well. looking for thoughts. have thought about upgraded units, but retired and money is an issue. original OEM has held up well, Suncoast or BTS would add several thousand dollars to OEM replacements. would appreciate thoughts and comments.
