94 TS magna transmission problem
 

Good day everyone .I am not sure if this is the rite place to put this .. I have just replaced the auto in the wifes magna the replacement auto is from a wreckers that has been recorded 3 months ago . the auto wont go into 1st 2nd . it just takes off in top gear .. wont kick down . wont manually shift into the lower gears as well.the overdrive doesn't make any difference as well. since i replaced the auto the taco/rev counter seems to be about a 1000 revs out - higher than the actual engine revs i don't know if the D light in the dash display is flashing or not the light doesn't work . I am wondering if it could be electrical issue or something easy to fix .. the nearest Mitsubishi fella is 140 kl ms away.. if anyone can point me in the rite direction the help would be greatly appreciated....PS 94 TS sedan east west engine 2600

Maybe a different Forum instead of a Mustang site.
