Hi please help my Isuzu 4L 30 E auto transmission bump when down change I have been changed all solenoid but the same problems so what it wrong ? Thanks
what isuzu is this, model car or truck
no model stated. (wild guess RODEO)
no year stated, 1991 to 2001 used.
no engine size state or of gas(petrol) or diesel
zero input just 4l30e box, lots of those
so Ill daftly guess.car
it's a car a ,(see list at end)
and has TCM that shifts those solenoids.
check fuses yet?
scan it yet, scan it to see all those TCM errors yet?DTC P07xx errors>
why change the solenoids.??? hard work for a guess.
only when it downs shifts, but all lower gears?
or 3>2 only.
the Tcm SHIFTs the box.
it shifts based on
and driver demands.
this are all sensors. every one.
just like on new cars.
the TCM (brain) can go to limphome mode
and guess what?, it will shift funny,for sure.
crude as h3ll and may skip gears (and more)
that you think are harsh but in fact the skipping gear is the cause ,harsh is effects.
All modern car ,needs a scan tool to work all cars
i guess you dont know that.?
get it scanned
buy the tool.
no car stated, so can't wax too savvy!
not at all.
is car in USA?
the book shows this.
"High Flow" Pulse Width Modulated
Solenoid (for 3-2 Downshifts Only)
id bet, limphome mode cancels this modulation...!
runs highest/newest # DEXRON fluid, (VI)
are levels at spec. not overfilled, using correct method of the BOOK.???
