trans is in limp mode due to a problem internally of trans. see pic for problems you can check a couple of these like a connector but more than likely a clutch pak or internal problem.

the inner speed sensor if not reading could cause this. sorry abou the pic I forgot to post it but will now. this is definitely a trans problem or electrical. it may be the can bus is messed up which a pro will have to look at with his scanner to see. but the tcm has set the 1529 code so it gets straightened out then it may be able to be erased and fixed.

if the engine runs good then no need to change crank sensor this is a trans problem not an engine problem. disregard the second pic where it says crank sensor that was for another car I goofed again just the first pic.

Just a thought but would a bad CV shaft cause the limp mode?

no it's either internal to trans which I think is or what I've sent you previously
