jbrunson Report post Posted February 20, 2015 OK... our next candidate is a 1994 Allegro Bay M35 with a 230 hp Cummins, 4 speed Allison and Oshkosh chassis. Am I correct that Freightliner bought Oshkosh? And can I expect to get parts for this from the nice folks in Gaffney? Can anyone point out the weak points of this coach? What would be a treasonable expectation to install exhaust brakes on this machine? Where would I go to discover the towing capacity? Share this post Link to post Share on other sites
wolfe10 Report post Posted February 20, 2015 Yes, Freightliner bought Oskhosh chassis division. I would call Freightliner, Gaffney (Freightliner 800 385-4357) and ask them the support question. Having the VIN would give you the best answer. One of the limiters of installing an exhaust brake is the 4 speed Allison. The torque converter does not stay locked up in lower gears, so you can generate a LOT of heat in the transmission on long downgrades with the exhaust brake on. I would call Allison with the transmission model number to verify what you should/should not do: Allison help line 800 252 5283 Share this post Link to post Share on other sites
