I think my tranny is about to go and i was hopeing someone would put me in the right direction to what i should put in my 98 f150 4x4. I need somthing to withstand harsh conditions and maybe not so expensive. Thanks for your time and effort.


Thanks
Bobby

 

I would buy a later model 5.4 transmission and install it in there. With a few minor modifications that would be a very strong unit.

thanks for the inforfamtion.

 

Bobby, What transmission do you have? I recommend that you take your truck to a reputable transmission shop and have a diagnostic test run on it. Sometimes the electrical part of these new transmissions can give you the feeling that trans is going. If the shop tries to push a rebuild without running the diagnostic find another shop. Shawn

 

I wouldn't even rebuild the 98 unit. Put in a later model 5.4 unit and be done with it. These units improved every year. 98 is a major improvement over 97 because of the mechanical diode. 99 is a major improvement over 98 because of the valvebody. 2003(and any 5.4) transmissions have stronger hard parts.
If the problem is electrical you should get a flashing od light. Unless it is a sticky epc solenoid which will either give hard or soft shifts, usually only when cold or warm. Some act up only when cold and work fine when warmed. Some act great cold but begin to act up when warmed.

Thanks for everything.
