I hve 266k on my 1984 300DT tranny and the slips and thumps are getting abit more everyday so i think i'm in the horizon for a tranny change. I've had the tranny modulator, bowden cable and vacuum system all checked out.. I've read some posts(bad stories) about getting a rebuilt tranny from sources other than the factory. My indy quoted me a factory rebuilt tranny plus labor for $2400.00...sound reasonable? I already posted a querry for Caliber Motors in Anaheim ,Ca...a MBCA member who works there gives MBCA members a discount. Do you guys know of other reputable sources for trannys...hopefully in or around Southern California? Thanks again.
