My 1999 dodge 1500 truck 5.9 engine is stuck in 3rd or4thgear on my automatic transmission. what do I do????

no engine told. size, this tells what transmission sites behind it.
1999 Dodge RAM 1500????? not VAN. 1500
2wd or 4wd'/
5 engines. then.
check all fuses, some have stand alone TCM brain (tranny)
scan the PCM for P07xx error (tranny)
check ATF levels hot, park ,idle, only do not overfill it ever.
ATF+3 (not sure but do check)
they used 3 transmission then
4-speed 42RH-RE automatic
4-speed 46RH-RE automatic
4-speed 47RH-RE automatic

42RE , is electronic shifted,
OD gear is dead or just the TCC lockup deaD
best is count the gears more carefully to see truth.
yes 4th gear is OD Geared. 3rd gear is 1:1 lockup.
.74-to-1 for first, 1.54-to-1 for second, direct 1.00-to-1 for third and 0.69-to-1 for fourth.(OD)
scab the PCM
to see if errors from the transmission show up.
I bet they do.
the 3>4 shift solenoid must work, .and no pressure errors.
the schematics show an OD switch if not closed OD does not happen, forget about that switch>
if car is 4wd and is in 4wd, many cars/ and truck all shut off
OD in 4wd, by logic inside the PCM (pure) my not be true on the biggest engine not told.

When did you last replace trans filter and fluid? Dirt may be causing shift valve to stick.

If you only have 5 volts you may have a bad battery or alternator. Or maybe a B+ (battery positive) wire short to ground. Check voltage engine running at the battery then alternator +. If your voltage is that low your TCM won't work.

no diff shift point computer wont work

yes

according to the owners amnual the max towing weight for a 1999 ram 1500 quad cab wit automatic transmission is 7600 lb.
with either 5.2 or 5.9 v8. for a reg cab it is 8000 lb.

With truck running check transmission fluid level add if low

Look on the gearshift lever. You will have remove the cover to get to it.

your ultradrive transmisson has failed, and your stuck in limp home mode. you have 3rd and reverse.

that was the good news.


the bad is that you need a new transmission. the ultradrive transmissions are very problematic. do a wikipedia.org search on chyrsler ultradrives and than write a really angry letter.

your not the only one that transmission has left of the side of the road
