tranny o/d issue
 

whats up people new here so let me say whats up 1st..

having some problems with the overdrive in my auto tranny.. just replaced the old one with a rebuilt. everything is moving ok (as in no grinding) but when i switch to OD the car looses maybe 70% of its power and the o/d light flashes but this only happens every so often ive checked the sensors, grounds. even the mass air and i have no clue as to whats going on

thanks in advance

this is the diagnosis system for the auto tranny, go thru the steps and let us know what codes ya got :)

thanks.. but i was drivng the car to work today and one of the water lines busted as i was idling in the shop's parking lot..ill have to get the codes tomorrow

what i get for paying $700 american for a car who's owner didnt do a freaking thing to keep it running

had the car a little over 3 months here's what i've replaced..

tranny
heater line
line coming out of the radiator
headers/exhaust
mass air assm.
took off venom sticker on an all stock car =/

whats STILL wrong

dash lights go out when headlamps are on(fuses good)
headlights wont stay bright
targa top is leaking
6 way driver seat is only a 2 way
car smells like stale beer and a pine tree freshener

and my apologies for not including the year. its an 88


i miss my teg =[ but the supra will be a killer in about 2 years =]

ok this is starting to piss me off... did the self diag.

just gave me an "error" message

took off the bumper cover, and both fenders looking for a short/scrumped up wire nothing all grounds are good


i just got on the phone with a friend told me to check the vacuum lines...
i have no diagram to go by so heres whats happening


extreme loss of power under heavy exeleration(both in overdrive and normal)

sometimes at idle the car goes from 900 rpm's to almost stalling out

temp gauge goes from the normal temp to no temp what so ever but car is not running hot AT ALL

and as said above ive checked the fuses they are good..

im thinking i should reset the ecu but im kinda scared to dive in that deep



im stumped to this...
