2003 MDX Shaking
 

At 83,000 my transmission blew. I had the transmission replaced with an Acura factory transmission. 34,000 miles later, I am beginning to feel on a daily basis a shaking of the entire car when I slowly accelerate from speeds between 20 and 40 mph. I took the vehicle in for service and I was told no problems were found (no error codes, etc). As the replacement transmission only has a warranty 3/36, I am afraid that at 37,000 the transmission will blow and Acura will say "too bad". I felt the exact same shaking feeling before my prior transmission blew. Generally it is about 3 or 4 quick shakes and then it stops. The other day, however, it lasted for about 4 or 5 seconds. Any advice?

BTW, it is not me causing this problem...I purchased the car at 76,000 miles and it blew at 83,000. I drive the car like gas is a precious commodity!
