Hi, I am a professional certified mechanic, with an engineering background, and 35+ years experience. I will do my best to assist you. Also keep in mind I don't know if you are a pro or a novice, so feel free to add any additional info at any time.
There is a flange on the rear of the block that the transmission bolts to. On the drivers side bottom of the flange is the engine serial number. The last 6 digits should match the last 6 numbers on your VIN. Also I have been in the auto repair business for over 35 years, and if anyone keeps your vehicle for over 30 days something is up. A year is lawsuit material, there is no excuse for that. Go over all of this and if you have any more questions at all, I am here to help. Good luck with it, have a great day, and Thanks for using Just Answer.
I do not get paid for my work unless you rate at 3 to 5 Smiley Faces or Stars, a bonus is always greatly appreciated. If the answer is not clear, let me know what additional help you need, and I will be happy to assist you further.
