no speedometer and no shift

[grandprixgtp_93]

ok so i got the gtp running and it sounds great but now i have an issue. when you put the car into gear it automatically defaults to 3rd and will not accelerate like it should or down shift and my speedometer and hud dont work. i have a funny feeling these problems are related and has todo with the vehicle speed sensor in the end of the trans by the differential. but im not 100% sure

That's what I would check first.

4t60e's are electronically controlled shift wise and they use the speed sensor to shift, if its not present then the car defaults to third gear limp mode.

sweet that answers my question right there cuz im in 3rd gear limp mode it was really upsetting to have this happen right after i get it running after a year of down time
