Questionmy 97 voyager went into limp mode giving a fault code #24. I changed the fluid and filter but a curious if it possible to fix with a whole trans rebuild. Seem like when you go to the trans shop the first thing that come out their mouth is rebuild. what are my options first to check before a rebuild.
AnswerHi John,
I believe you are correct in resisting a rebuild without further investigation. The possible reasons for the code include several that are not cured by a rebuild, but if all those prove to not be present then removing and opening the trans would be appropriate.
The possibilities are:
low/high trans fluid level
short or open in LR pressure switch circuit
solenoid pack internal problem
40-way connector problem (9, 47, or 50 cavity)
control module failure
and then internal transmission problem (the rebuild).
Another table lists these possibilities:
faulty cooling system
torque converter clutch failure (that requires removal)
internal solenoid leak
too high or too low pressure
valve body leak
regulator valve
stuck/sticky valves
worn or damaged accumulator seal rings
damaged clutch seals
damaged L/R clutch
worn pump
Only the seal rings and L/R clutch damage and torque converter clutch failure would dictate a rebuild.
All the other items are serviceable without removing the trans, and involve the solenoid box for the most part which is external and accessible. So armed with these possible causes I would shop around to find a trans shop that would take a look at the alternatives to a rebuild job. The rebuild is in the range of $2k, so spending some time on the alternatives seems to be in order.
