Loan my truck to a friend she drove it with no transmission fluid in it I put 4 quarts of fluid in it now it will go in reverse but it will not go forward.
What is your question?
Does this mean that the transmission is no good now and I need to replace it.
RepairPal Certified shops can diagnose and repair your 1994 Mazda B4000. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
IF transmission fluid is at the proper level and the transmission still will not engage - then yes the transmission will need to be rebuilt or replaced.
