Have a 1992 E 250 van. Bought new. Has auto transmission I think it called
an E04. Always maintained as user book shows. Has 51000 miles. Ever since
new it seems there is too much slippage when starting up in gear. Engine
races too much, not a positive acceleration. Other brands I have had GM and
Infiniti have a much more solid take off. SO is this the nature of the
beast or could it be corrected with a different chip in the computer or what
else. However in back country use no problem with sufficient power on steep
stuff. Any ideas are welcome. This is first time to this site. W W

If tranny is slipping, not chip will fix that but what are you basing
the slipping theory on? What is your engine RPM durring these times?

If you have the 5.0L engine, the trans also has a higher
stall converter which make it seem like it is slipping.
Another thing that can make it sound like it is slipping
unusually is a bad fan clutch keeping the fan engaged too
much. This makes the engine sound louder and will also take
a lot of power to drive that may make the vehicle feel a bit
sluggish as if the trans is slipping. I get this in hot
weather a lot especially when in traffice with the a/c
running full boogy. Basically, if the E4OD is slipping
excessively, it will set a fault code and start flashing the
OD cancel light.

Kinda my thoughts here too. That is why I was asking what he was
basing his "spilling" theroy on, feel or actual RPM.

The nature of the beast is to seem a bit sloppy and not produce very
solid shifts, but that doesn't mean it's designed to slip. Heed
Lugnut's advise. I'd recommend that if you have the ability, to check
out the trans yourself; if not, take the van to a qualified repair
facility. If all checks out to be fine, then you may want to consider
getting a tuner chip, trans command module, different torque converter,
and/or performance rebuild kit. Don't however, just make a performance
mod before making sure the trans is already in good condition - doing
so, will shorten the life of the trans.

Thanks to all that replied. Will check out all that was noted . I don't have
a tach on it. Trans has been this way since new. I made it into a mini
motor home and happy with the gas miles. Get 12 to 16 MPG. I do have the 5,0
engine. Weighs out at 8000 lbs. Warren
