Don't panic.... Don't get sucked into buying a bunch of stuff you don't need. Assuming you own it, first thing is what do you want to use it for? Silly question but it's the basis of what direction you want to go, daily driver? Since you are getting a vibration it sounds like you want to drive it on the highway? First, find out exactly what you bought. Do you do your own work or send it to a shop? Letting a shop tinker is extremely expensive. What are your limitations... be honest. Get a CD Factory Shop Manual, read it. Spend time in web sites and come to understand exactly what you have and where you want to go. When I bought my 04 Ltd I didn't know a 247 from a 242. The TC was a POS so I looked up what was needed. (247's are a POS) I found out ALL the pieces I needed to swap a 242 in. (Note: Lorado's come with 242, Ltd have 247) Went to one yard that had all the stuff and got it all at once, then took time to do the install right. Replaced the trans rear seal and TC seals. Got the cables, proper cable bracket and center console for the 242.That looks entirely wrong. Is it lifted? I had a 247 in my Ltd and swapped a 242 into it, no troubles for over 100,000 miles. The TC is bolted to the trans tailshaft? Look at the rear of the TC and take the data off the tag.
