HOt engine, or cold engine or both???????????????
Gas or Diesel? what engine>? 4 speed A/T right?
first off the CEL only glows for smog fails, many other DTC errors
all important , only show up on a real scan tool. even a $9 tool this old car.
is it the tranny or the engine hunting, that takes, skill to know.
any mech , can tell you ,easy.
does the engine run prefect , get to 180F + temp and hold?
does the enigine hold 800 RPM steady hot idle in park.
then select Drive, foot on brake pedal and still hold this normal idle spee?d. , yes, then good.
this hunting, i cant understand that.
does it upshift to all gears, correctly?
and down shift.?
and does it not hold one gear. at cruise? flat ground.
does it not down shift with fast deep throttle.
does not down shift on hills.
exactly when does it hunt, you doing what?, in drive, im guess.
tell driving conditions, and right foot actions.
my FSM has over 50 A/T symtoms. the A/T is complex.
a driver (mech) will do many tests driving to see what works and what dont.. (both)
BTW2: i never pay any attention to any CEL lamp, I SCAN all cars.
The newer the car , the more DTC's , the key is to NOT MISS THEM.
Your A/T may be electronically shifted, and if yes, it's got a TCM
(either the TCM box or is part of the PCM )
either why. ,make sure the TCM never sees errors, ever.
there are many inputs to any TCM and all must be correct or the tranny will shift wrong, or go to limphome mode.
here is the wiki.
Transmissions for the Ram
- A500/42RH-RE lower geared light duty applications found behind the 3.9 L V6,
- A518/46RH-RE for more heavy duty applications found behind the 5.2 L and 5.9 L V8 engines.
- A618/47RH-RE for heavy duty use behind the V10 gasoline and Cummins diesel engines. The 47RH was used in 1994 and 1995 model years, while the 47RE was used from 1996 through 2002.
and up are manual trans,
so by wiki I see all 3 are electric, SCAN it now , with a full scan tool.
each tanny ending in "E" is a TCM shifted "E"lectronic shifted trans.
so post what you have, as i can not guess.
my guess is 46RH
