This video is about rebuilding a 68RFE transmission. The video is part two of a series, covering the assembly process after the transmission has been taken apart and cleaned.
The video focuses on the importance of replacing transmission bushings for proper gear train function. Worn bushings can cause the gear train to hang and flop, misaligning the sealing rings and causing leaks. Replacing bushings ensures that everything is centered and true, and this is demonstrated with a visual inspection of the lack of side-to-side wiggle in the parts.
**The presenter emphasizes the importance of using high quality parts**, specifically mentioning BorgWarner frictions. The video highlights several instances where updated parts should be used, such as a one-piece bushing replacing two original bushings.
**The video provides detailed information about the assembly process, including:**
* Using specific tools like bushing drivers, cutters, and a shop press.
* Lubricating parts with assembly lube, differentiating between the green lube for bearings and the blue lube for o-rings and seals.
* Identifying the correct orientation for various parts, such as washers and snap rings.
* Installing clutches and frictions, differentiating between under drive and overdrive frictions by thickness.
* Assembling the low reverse drum and installing it in the case.
* Replacing the filter in the drum with an orifice cup plug.
* Assembling the input drum, detailing the installation of o-rings and lip seals.
* Replacing the torque converter clutch seating rings.
* Inspecting and reassembling a remanufactured pump, correcting the orientation of a gear.
* Installing shift kit components in the pump.
* Rebuilding the valve body, detailing the installation of accumulators, seals, and check balls.
* Installing the valve body in the case, and highlighting the importance of proper seating.
* Installing the filter and demonstrating the correct installation procedure to ensure proper seating.
* Replacing the line pressure sensor.
The video concludes by mentioning the importance of replacing bushings in transmission rebuilds, drawing a comparison to the necessity of replacing cam bearings in engine rebuilds. The video also promotes other content on the channel, such as videos about bushing installation and the 4L60 transmission.
