When i take off driving my truck it shifts from 1gear to 2gear fine but when it shifts from 3 to 4 my truck starts shakeing real bad. If I even bearly touch the gas the transmisson starts to pop. The only way for it to not start poping is to slam on the gas so it shifts down to a lower gear. I have a nice truck and I wish I could get this fixed. All in all, if have any info to whats wrong with it and the price to get it fixed it would be very appricated.
