94 F350 Transmission Leak Help
Can someone tell me if I should buy or stay away from a truck I am looking to purchase. The owner says that at times the truck will blow out about 1/2 quart of tranny fluid through small tube near oil pan. The truck is 94 F350 Diesel 4x4 crew cab. Is this normal or not. Thanks, Randy <!-- / message --><!-- BEGIN TEMPLATE: ad_showthread_firstpost_sig --><!-- END TEMPLATE: ad_showthread_firstpost_sig -->

The front torque convertor seal can leak if heavy towing was done..... it can sometimes reseat itself and be fine for a long time. The trans would need to be R&Rd to repair it, the 94 trans was updated to be better than earlier year E4ODs, but if it must come out think to have it checked for most recent applicable UPGRADES reqiured not just rebuilt.

the front seal is damaged due to being overheated
could be from abuse or from a torque converter clutch that is slipping and causing it too overheat it does have tocome out
the only mod you need to do is a pump modifictaion kit from superior transmission it will correct tcc apply and correct lube circuit issues also

Thanks. It looks like I'll be picking up a gasser with a bum front seal on the tranny, so this is very handy, and timely information

Something else I wonder is if it already overheated once or twice, there may be other internal issues. A partially blocked cooler might be causeing the overheating, but what got into the cooler to cause the restriction? Might be as simple as a kinked line, but the risk is that internal parts are tearing up.
Heres the pump kit that was mentioned:
4L60E, 700R4, 4L80E, 4R100, E4OD, 2004R, C6, TH350, TH400 Transmission: SUPERIOR E40D PUMP CORRECTION PACKAGE
I wonder what years this kit best applies to. My book shows changes to orifice holes that were intended for 1989-1991 models to increase the flow of some holes in those years of transmisison pumps (among other changes).

i dont know what book you are referring to but the early pumps are replaced by the late pumps
in all the years i have worked on them there was never an orifice difference unless you are referring to the modulated tcc pumps versus the non-modulated tcc pumps
and the kit works on all models of the E40D plus the 4R100
