So i recently bought a 1996 4.9 4wd truck with only about 88,000 miles. When first driving it i didnt really notice a thing. A few days later i started to feel a "kick" and some vibrating noise when accelerating from first to second. The truck has the e40D transmission. I decided to do a transmission oil change and to my luck i the oil pan and magnet were pretty much free of any metal shavings. The magnet did have a good amount of sludge but i know thats normal. The transfer case barely had a quart of oil and was extremely burnt. I also drained out the torque converter. So after doing the maintenance, the vibrating noise is still there. I went through all the sensors and found many of them pretty dirty so i cleaned them (just for now) and the kicking seem to stop. The noise though is still there, any suggestions of what it could be?
Thank you both for your response by the way! And I will check it out right now but also yesterday I stepped on it pretty hard going about 20 and it reved up and the vibrating intensified all the way to 35
Another thing I see is when I put the truck in reverse or drive it has a little delay, just a few seconds to it goes into gear. When I put it on 1st it like does a little jump
In my experience, you cannot tell a bad u-joint for sure without removing the driveshaft.
Absolutely true!

I'm already checking it out but what do you all think my truck has that little delay? When shifting from reverse to drive? And that little jump when I put it to 1st?
My '95 does that too, and the transmission was rebuilt in September. My old '69 F250 with a C6 did it as well; before and after I rebuilt it. In fact I'm pretty sure every heavy duty automatic truck I've driven has done that.
As others have stated, that sounds like a bad u-joints or both u-joints.
Mileage is low, but internally, they can be bad.
I had the exact same problem when I bought my '95, 302, Eddie Bauer 4wd. I asked the owner and he said the rear joint was bad...And it was BAD. It kicked and bucked. I made him sign a paper stating that if it didn't make it back to my residence due to the damaged u-joint, he would hand me the money back and he could haul it away at his expense. I had to drive 85 miles with hills and interstate. Luckily I had a friend that drove his truck in case I encountered problems.

Those are characteristics of the E4OD transmission.
