I have a 98 Tahoe 4x4... I need to know How would you find the Transmission Code on the Service Sticker in the glove Box... and How many different Trannys did GM make for that Truck. it's a 5.7 Vortech.. and one more thing does any one in the Washington DC or Maryland area have one for Sale?


Thanks..

I would "GUESS" that your truck came with a 4L60E tranny, the RPO code in the glove box however should start with an M, for example, for the 4L60E it would be M30. Below is a list of all of the Chevy transmission rpo codes for narrowing it down once you find it.
