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

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.
