i took my TA to a transmision shop cuss my car wont go into 4rth
il be doin about 60-70 mph and it wont shift into 4rth.

they said the trany is in good condition but that the 4rth seems to be stuck,they told me to go buy some tranmision treatment fluid to fix the problem.

my car is automatic its a TA 1994 GT.

any advices? what do u guys think, i dont trust this guys,they seemed lazy.
