When accelerating from a stop, the engines revs up to really high RPM’s before shifting hard into 2nd gear, and again while shifting hard into 3rd gear. This started in the last week. The engine/trans currently have ~133,000 miles. Accelerating slowly, not exceeding 1,500-1,700 RPM will reduce this occurence, but it takes significantly longer to get up to speed, which is a problem when entering 55 MPH traffic. We’ve had to pull off the road to avoid causing an accident while merging with traffic since the transmission seems like it won’t shift, causing me to have to let off the accelerator to try and allow the transmission to shift so I can continue accelerating.
