I finally got around to swapping the original transmission out of the 4runner. While I was celebrating the odometer rolling over on 300,000 miles I realized that it was time to get this done.
What I did here was swap out the original G58 5 speed transmission and chain driven transfer case with a rebuilt W56 transmission and transfer case from a 1986 4runner. This is one of the stronger 4 cylinder combinations available from Toyota, which makes it a good swap. At the same time I also switched out the stock 2.28 low range gear set with a 4.7 gear set almost lowering my ratio by double. At the same time I also swapped in a twin stick shifter that allows for seperate operation of high and low range as well as two and four wheel drive. To top it off I finished off the swap with a new budbuilt crossmember and skid plate.
I’m looking forward to getting out for some wheeling soon to try it out. The little bit of testing I did was impressive. The low range gears are extremely helpful for getting over and throught tight spots.
