MLM 57 Report post Posted July 1, 2011 Hi Guys, Not a personal question but one asked by a collegue. Hoping someone would have a feel for this. Q: I have a E46 325 4 dr Motorsport and intend to use it for towing a trailer with most likley a race car on it.(formula ford) I have heard there are issues with this series of car where the auto box fails when towing. Is there any truth to this or should a properly maitained and driven trans survive just fine? Its the difference between fitting a tow bar or buying a new car. If you guys can help that would be great. Quote Share this post Link to post Share on other sites
hybrid 1043 Report post Posted July 1, 2011 The biggest problem with these gearboxes is cooling. If your gearbox cooling system is all up to scratch and you are towing weight with-in the chassis limits their should be no problem. Problems come when people tow with a fault heat exchanger and/or radiator cooling issues (used as part of the GB cooling solution) Other issues are if you have worn drums and/or valve guide body causing thumps thus loading up the auto clutch packs in-turn causing more heat and degrading or breaking down the auto trans-fluid.
