Vixed 21TD 5spd Turbo diesel pusher motorhomes are known for their excessively high first gears and rubbery shift linkage contolling the trans axle some 20' behind it. We are interested in converting the Renault transaxle to an Allison 3000MH. We have a full machine shop, so custom fabrication is not much of an issue. I would like your opinion re: * Cost of the transmission itself (NEW) and/or the likelyhood of locating a used unit to save $$$ ** The general concept and any special things we should watch out for in taking on this task. Thanks for your help!!!
