P0700 just tells you the problem is serious enough to turn on the CEL. The real malfunction codes need to be rear.

Which tune do you have loaded from the predator and how long have you had it loaded?

go to advance or auto zone and get all of the codes read. As others have said the P0700 is just telling you that there are codes in the TCM that your predator cannot read. You may have a fueling problem thats causing your tranny to act up, its hard to say though.

im having the same problem, if i spin out in a puddle of water (i have a heavy foot), when i get up to about 70 it downshifts and throws that code. I can clear it out with the predator and it will drive normal until i spin out again. any ideas? dont mean to steal ur thread i just really need to know what the heck is wrong.

When you bang your head against the wall and get a headache, and then you do it again and still get another headache: you might not want to bang your head anymore if you're smart.:D

i get the same code when i run my tuner on Extreme, my local mecanic said that it may be a selinoid on/in the tranny that needs to be replaced.
