Hello
I have an 07 Tahoe and the trans went out I was told I had a 4l60E transmission. when I ordered a new Trans from Monster Transmissions and provided my VIN they told me that according to my Vin I actually had the 4l65E. I had my nephew replace the trans for me and shortly after driving it for about a week I started getting codes P0717 & P0700 and didn't know why so I contacted MT about this and they said My original trans was a 4L700E and that I needed to now pay them a restocking fee plus shipping to swap the transmission almost an additional $1000. my question is what is the difference between these 2 transmissions and do I have to swap them? Aside from the codes it seems to run and drive fine ( it does shift more aggressively 1st into second and 2nd into third ) but it is a performance trans with a corvette servo.
