I got a new transmission but the gears are still slipping into neutral mode

What is your question?

Hi, I bought a 2008 Suzuki Grand Vitara Ltd Edition in December. Apparently it was towed for most of it's life. It started slipping out of drive to neutral and so took to transmission place. They replaced transmission but it still does the same thing as before. I have to drop it down to 3rd to re-engage it to go Any help would be appreciated. It is sitting in transmission shop for 3rd time while they try to recreate the problem

How long has your 2008 Suzuki Grand Vitara had this problem?

Since I bought it 10 months ago
