Most likely it could be a vaccum prob. With the engine running spray windex or soap and water on the lines to check for leaks. If bobbles appear then replace the hoses. There could also be a electric problem.
How warm are you talking about. Normal? Very hot?

I have a 2000 Jeep Wrangler. It is a 3 speed automatic and it is now not shifting into 2nd gear. It goes from low to 3rd. Could this be deteriorated vacuum line?


no TCM ,means its a hyrdamatic box. (old skool. old ways)
it has no vacuum modulator, if you read the free FSM posted here 300 times you'd see there is none.
is uses a governor. to shift. and TV cable to delay shifts.
there is no magic limphome here.
here is the free book again 301th time.
http://www.morris4x4center.com/knowledge-base/index.htm?utm_source=cj#service

see chapter 21, trans. TJ 2000 jeep
see choices? 30/32RH
the 2 boxes match your unstated engine.

I have a 99 jeep it started acting crazy and checked the oil the dip stick said it was bone dry so I put 3 quarts in it and checked the oil again and this time it was about 3 quarts to much


my guess is you used the wrong dip stick,
i cant watch you mess up. so....no jeep stated a 99 what?
wrangler, Cherokee or grand Cherokee?
so i bet you have an automatic trans, right?
then pulled the dip stick on trans thinking its the engine
or the reverse. bad news if true.
rigth?
find someone that knows the difference or read the lost operators guide.

and error 2, the stick empty is not bone dry, not ever.
yes real low. so and 1/2 quart at a time , not 3 qt ever.
until the engine stick is at normal..

if this is a transmission, and you put engine oil in there
all hope is lost. and the method is hot running, to add ATF fluids.
unlike the engine method.
my best guess totally BLIND>

2003 jeep wrangler 4x4 auto...transmission is not engaging at all, i.e.not in park, drive, reverse, 2wd, 4hi or 4low...how do I fix it?


Did you check your ATF level? I have an ATF leak somewhere and when my ATF gets really low my auto trans will keep slipping out of gear until I dump another quart or two of ATF fluid into the trans.

How do you know if your torque converter is bad on Jeep wrangler


First check fluid. Make sure it's full and clean and does not smell burned (compare to another good car)
Converter failure is usually most obvious when trans shifts to OD. if shift is late or makes bang noise going in, you likely have a problem. to check lockup, after od engages, lightly touch brake, trans should momentarily shift out of od. Whining is usually due to low fluid. Also check transfer case and both differentials for proper level and leaks.
