ok i got a 93 bronco
5.0 stock
e4od trans
3.08 gears
33x12.50r15 all terrains
6" bds lift
134000 miles

The trans just started shuttering trans fluid looks ok not burnt it dont do it when its cold only after warm up i tried some lucas trans additive didnt help should i get it back flushed? or drop the pan drain the convertor and re fill with new fluid and filter?

 

I did the later and glad I did. Messy job but worth it. The magnet had 2-3 tablespoons of metallic goo around it and I guessed the filter had goo in it too. Shift points and down shifts improved greatly as a result. Remember to get the old gasket out when you pull the filter if it is not on the filter neck.

 

definatly put new fluid and filter in there. also pull the tranny codes.

on a side note double check your axle gear ratio. 3.08's werent installed on a bronco with a 302.

 

Stock gearing for a 93 with a 302 (5.0) is 3.55 with 4.11's having been an option. And 33's with 3.08's????! OMG! Does the E4OD EVER get into overdrive? I mistakenly ran 33's with 3.55's in my 92 for a while... tranny spent more time hunting for the right gear than I spend hunting for Bronco answers!

 

I ran My old Bronco on 35's for awile with 3.55's. It would even look at a hill in overdrive. The AOD bernt up the first gear in about a year. I guess 33's would last a little longer.

 

Changed filter and fluid much better also checked axle tag 3.55 gears the truck shifts and runs much better next step put some gears in her and rebuild the motor Thanks For The Info Josh

 

do the gears first so you save the rest of the drivetrain from undue strain. if your planning on running 35's be sure to gear for that.

 

i plan on at least 4.56 w/arb air lockers since i only drive to and from work which is only 10 miles round trip

 

in that case you might consider 4.88's at 70mph i am at 2200-2400rpms in OD

 

So, Kem, you are @ 2200-2400/70mph with 4.88's in OD? Makes me wonder if I should consider going taller than 4.11's with 33/34's. Guess I need to research the ratios in the M5 first and see how they compare with the E4OD.
