The transmission works just fine when i dont stomp it down but i cannot go full throttle because it wont shift. the car redlines its self. i can only go about 3/4 throttle. is this a computer problem? any ideas?!??!
.id have to drive the car and see at what position the throttel is whene it doesnt shift.my bet is the either oil and filter change or TP sensor.Check TP sensor.inspect the tranny oil. Feel it,t,smell it. does it smell burnt? is it to milky? does it lack oil? is oil too full. these are some basic procedures in diognosting this sort of problem.

That is a possibility (call a dealer to find out for sure), but the simplest answer may be the throttle kickdown cable, which is common on most vehicles. It monitors throttle position (for instance, to tell the transmission that you just stomped the gas pedal to merge onto the freeway in front of a tractor trailer that is hauling but in your direction, so it needs to shift down quickly for some much needed acceleration). I have solved a few shift point problems by walking through the simple kickdown cable adjustment process, which can take as little as 5 minutes. You probably already checked the fluid level, but check it carefully, per the manual, on level ground, if you weren\'t that picky the first time. Some transmissions are much more sensitive to fluid level than others. All this assumes that the transmission was known to have no issues before you installed it, of course.
Sorry your rebuilt trans did not fix your problem P1120 is TPS out of range The throttle position sensor responds to the gas pedal movement . of speed and angle it is moved Most sensors are 3 wired which has a supplied voltage of 5 volts and a ground and a signal return voltage this signal starts around .5 volts closed throttle plate and slowly works to 5 volts at full open position with a volt meter test the return signal while operating the throttle plate (engine off key on) look for glitches is voltage span go slow if this test fine check at computer the wire can be broken somewhere.
check your Idle air valve thats what keeps your car with the right air mixture or check you idle screw for proper rpms usually they are under 1000 rpm 950 around there but i suspect it might be you air valve sensor the idle screw usually dont get outof adustment because if set from factory but is something you can look at
