Re: 700r4 loses all gears

does it make any weird sounds or noises? did u put it in? did u make sure everything was fastened tightly and that you put trans fluid in the torque converter, and did u make sure the torque converter was installed properly?

just ideas...

Re: 700r4 loses all gears

I think I know what is wrong with your Trans who ever you bought it from cooked it (overheated it big time ) so when the temps get up inside of it the clutches slpig big time and probley the planetry gear are also shot does it wine after a few seconds and also when it is not working after the 300 yards you can throws it in any gear but park and nothing happens if you it was likei said cooked ( happened to my friend with the car i got now ) what it is the person who had it before you ran it way to long low i mean LOW on trans fluid as in almsot none on stick you need it rebuilt sorry
