Are the TH400 prone to leaking front seals? Reason I ask is my new to me M1008 has a trans leak. At first I thought it was the trans pan loose as fluid seemed to be seeping out around pan/gasket. Tightened that uop over the weekend and still have a pudle under my truck everytime I stop for more than a couple of hours. Any help will be greatly appreciated.
If one is leaking, buy a full gasket kit and replace all the external seals at one time. Just recently did this on another T400 I have for another project. Easier to do it once then continue to do them as they leak. Don't forget the selector shaft as it will cause a leak and can be a PITA to figure out.
