I have a 92 sigma 3000V, some months ago, around town, 50khph, with the OD on, the transmission started to cylce through the gears and not stay in one gear, paritcularly on a long streach of road. The problem wouldn't occur if the OD button was off. So, I just did a change of the tranmission fluid, the old stuff looked good, clearsih red colour but there was no real effect on the shifting of gears. Then two other problems started happening. Occasionaly, when stationary, shifting to D, the car stalls, or when driving for a while, the transmission shifts into neutral, the selector doesn't, but there is no drive to the wheels and the engine revs and revs.
Possible faults - *check the shifting cable selector is aligned with the neutral starting switch * check engine mounts *make sure the fluid level is between the marks on the dipstick running hot * overdrive friction and drive plates have worn out * the torque converter or oil pump has a problem *do a torque converter stall test hope you used only mitsubishi automatic oil when changed *check the throttle position sensor * temp sensor for the auto the TCU has faults or needs to be replaced

Two things happen on the Dodge's. 1. the rear O2 sensor shorts out and meses things up. 2. the Inner seal on the Direct drum (3rd) shrinks and causes a delayed up shift.
I would take it to 2 or 3 or more different shops and ask for an estimate to fix it.. they will probably know what causes this condition. and probably will not charge you anything.. if they want to charge you for an estimate go somewhere else. you really do not want to trust them.. When you get several estimates and several of them tell you the same thing then its a matter of who do you trust??.. Check the shops out on Yelp.. actually sounds like it could be something simple like throttle presure adjustment.. But i cannot see your car from here.
your transmission has external shift solonoids towards the front one is for 2 gears and the other for the other two i believe the lower one is the one you want ot replace they rust up and start binding inside.
The transmission may be in Limp mode. The transmission is on the same fuse as the MAF, O2 sensors and at
least one other sensor - if an O2 shorts out, it will blow the fuse and
the trans will go into limp-home mode. Be sure the trans has power and
the fuse is not blown before doing anything else.
What is "limp-home mode" ? This is a fault mode in which the
transmission either loses electrical power or the PCM deactivates all
of the electronics. The transmission will default to max line pressure.
The driver will have Reverse and 3rd, with manual 2nd available by
putting the gearshift in 2 or 1 (doesn't matter). 1st, 4th, and TCC
lockup will not be available. It will not hurt the car to drive it like
this for short periods, but use manual 2nd to get the car moving, and
be aware that the trans will generate more heat than normal while
operating in limp-home mode due to increased torque converter slippage
during 2nd gear starts and no lockup in 3rd gear.
Trans does not upshift out of first, speedometer reads zero at all times: VSS failure. Easy fix on rear of transmission, but xmember must come out to access VSS.
Car goes into gear but feels very sluggish like the brakes are dragging,
but it will roll easily (starts out in 4th gear), you manually shift to
2 to get it moving, once it's moving you put it back in OD and the car
shifts 3rd to 4th on its own and locks the converter at the appropriate
time: ShiftB solenoid failed: Easy fix in the pan. Or a wiring problem
from PCM to trans.. or PCM.
No 1st or 4th available; trans shifts 2nd to 3rd by itself in D or OD and locks the converter : ShiftA solenoid failed. Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.
Transmission does not shift automatically, only manually. Swap in a known-good PCM, check wiring, check other sensors such as VSS and TPS.
3rd gear starts, can manually shift through all gears. When car has
been turned off for a bit, then back on it will run normally.: VSS
dropoff w/ Hi-stall converter. The rpms are too high, but VSS is
showing no movement. Happens after a tire burning take-off. Doesn't
store a code, will not throw a CEL (I've heard that it will store a
code if it happens 3 or more times). Cure: Reprogram PCM for VSS
dropoff -- PCMforLess knows about it.
Here are just some of the common things you have described with the issues your transmission has. Good luck and keep me posted.
it would cost less to replace the transmission than to have that one rebuilt shop around and see if you cant find a trans for it and have someone put it in for you
