Hello I have a grand Cherokee with 129k Mile I noticed it started looking power when I accelerate my engine light turn on with the code p0732 -gear ratio error in 2nd secondary DTCS p2784 input speed sensor 1/2 I took it to some transmission spot and he’s telling me I need to rebuild my transmission I put transmission oil and is running fine but engine light still on I don’t feel it slipping and it changes gear into 2nd fine I took it to another spot and they basically go by what the paper says they don’t even test drive it I’m in nyc please help anyone
