Why does my 2001 toyota solara 5 speed leak transmission fluid?

no year car, no engine size, no transmission name , nor country
my guess this tranny A/t , fails 3 >4 shift/ that it?
fails to shift or shifts up and FLARE (aka false neutrals)
not told the problem at all just parts changed wrong
there are 50 causes (seals old and bad and leak vast)
and 20 or more bad symptoms on a failing tranny
FUN CARGO ,2 words called in JAPAN
Toyota Yaris Verso 2002 to 2004?
SCAN THE PCM YET/? p07XX ERRORS
I try to buy it on world market and see this.
TRANS UA-NCP25, (car code name)
TRANSVERSE BOX FWD.
BASE TRANS, AISIN, U340F-04A

THERE ARE MANY TEST. FOR ANY A/T
1: AFT not burnt, not overfilled or under
2: scans show what is wrong/ not scanned is no good.
3: line pressure port tested for a PSI in all shifted gears PRNDL.
4: if EBOX. , 3>4 solenoid bad, (not shifting to 4th)
5: PCVS some have pressure control valve, Ebox, to set or trim main line pressure. (as in modulated)
5a and newer have gear pressure detector switches.that can all fail if above fails.
6: all speed sensord good but the scans told you that if you looked.
7: endless leaks causes #3 to fail sure. its 20 years old why not?
maker AISIN , bet 1.
and some version of A340 but not told. ending in E,F,H,S
8:heat sensor in box (Ebox) that cause limphome mode to cool it down.does box work COLD"?
S code s Tip-tronic box,suffix code
my answer is mostly 2002 year, but NOT TOLD. U

a340f codes common
P0710 Transmission Fluid Temperature Sensor Circuit P0712 Transmission Fluid Temperature Sensor Circuit Low Input P0713 Transmission Fluid Temperature Sensor Circuit High Input P0722 Output Speed Sensor Circuit No Signal P0751 Shift Solenoid 'A' Performance or Stuck Off P0756 Shift Solenoid 'B' Performance or Stuck Off P2716 Pressure Control Solenoid ?D? Electrical P2740 Transmission Fluid Temperature Sensor B Circuit P2742 Transmission Fluid Temperature Sensor B Circuit Low top fix any trans, learn exactly what is there first
not guess, learn that, or even read its side plate tag
huge evolution 2000 to now, for sure new pressure control
modulated solenoids and 2 or 3 speed sensors.
Any car made,if has EBOx, (means TCM brain shifted )
must be scanned first after levels ATF correct hot.

sounds like you were running it without oil..that would explain why there was no oil leaking on the ground..the gearbox would now be worn out so it's best to get another trans,, could be a rebuilt or from a scrapped crashed vehicle..if the trans was running out of oil, best not try to repair it..

Sounds like you have low fluid levels in the transmission. I bet that when you do get a shift it really clonks into gear. Too much of that will rip the input shaft off on the splined end. Check the fluid dipstick for the transmission (not the one for the engine oil) and if low top it up to just short of the maximum. Do not use engine oil to top up it needs proper transmission fluid. If the fluid is low check that there are no drips coming from any leaks..sometimes leaks occur around the seal where the speed sender cable enters the transmission casing.

1. When was the Transmission Fluid and Filter Replaced. If not recently, have that done as soon as possible. I do not recommend the Super Transmission Flush as this does not replace the Filter.
2. Is there any leaks? What is the Transmission Fluid Level? Check while the Engine is Running and the normal operating temperature has been reached. If the Level correct? Any leaks should be repaired as-soon-as-possible.
3. Input Speed Sensor. Based on 2001 version, this could be fouled or going bad giving the Transmission the wrong information causing erratic shifting. On a 4-Speed Transmission this is located closest to the Solenoid, on the front of the transmission and at the level of the top of the Solenoid. Check the Sensors: Connections, remove, clean the inside end of Sensor, reinstall and check the shifting. If this does not fix: replace this Sensor.
Let me know if this helped, or if you have any additional information or questions. Feel free to contact me on FixYa.com!

whats leaking the speed sensor? if so sometimes the plastic portion of the sensor cracks invisible to the eye it must be replaced to fix the leak.

- There is no drain plug on the transmission. You will need to remove all bolts from trans oil pan.

SAFETY: Use Proper protective equipment. Jack stands, eye protection etc.

We like to use a garbage can lid with a small drain hole in it as a funnel, As it is larger than the pan and oil will seem like its coming from all directions. so try to let the pan fall from one side.

There is a magnet in the bottom of the pan, remove clean and replace.

This is a great time to also re-torque the valve body bolts. You will need a tech-manual for this.

Install new gasket. torque all bolts. Add fluid approx 4 quarts of the correct fluid and restart vehicle check fluid level often and check for leaks.

HAZMAT:
Ensure you properly dispose of the waste transmission fluid at your local hazmat center.

Hope this tip helps.

Sounds like a bad seal .is it leaking where the transmition connects to the engine
