Read multiple posts and not sure if my 93f350 e40d has TECA . Looked where the relay should be and don't see it due to relay location on this truck is not clear from previous posts . Also does this truck even have it ? I don't see the assembly or the relay anywhere . I have replaced vss , trans rebuilt, both sensors on side of tranny replaced as well as harness ends , psom rebuilt , fipl and harness replaced and adjusted and checked all fuses . Problem is hard shifting . I'm a year into this truck and still shifts hard . Please help
