This weekend I got my extreme valve body for wholesale automatic transmissions fitted, and also my Timbren front bump stops.
Let me start by saying this job isn't difficult at all, but you will want half a day and a hoist to do it. The auto in my car is the 5-speed (A750F). I'll do a run through of the fitment, with some pictures, however a fairly decent set of instructions are provided with the kit.
After you drain the oil, and pull the pan off, hold it under the auto to catch any oil that will come out of the filter body. You will want to leave an oil drain tray under the auto the hole time as fluid keeps leaking out as if it will never stop.
A quick before and after filter removal.
After removing the valve body, there is 19 bolts holding it in, I sat it beside the replacement, and began swapping the solenoids over. NOTE - be ready to catch the check valve and spring that will fall out of the auto housing when you pull the valve body out.
There are 4 solenoids held in like these two below,
Once you remove the plate, you need to remove the pin for each solenoid CAREFULLY! I only mention this because I pulled one out by hand and it slipped out and fell into an oil passage in the valve body and took me a while to eventually fish it back out!
Once you've done all that, you need to replace the 3 o-rings that go in the recesses along the bottom auto housing.
Then, get a friend or some assembly jelly to hold the check valve (where the pinky finger is) and one of the accumulators that fell out (index finger) in place while you fit the valve body back in place.
Once it was all fitted back on, with a new filter and pan gasket (supplied with the new valve body) I only had to fill it, now I should've known better, but I just went off the service book which said it takes 3.4 or something liters to fill after a fluid change. So I only bought a 4L tin from Toyota to do the job, of course a lot more than 4L drained from the auto in total, so I had to use the synthetic auto oil we had out on the property. It's dexron 2 so it is fine to use, however I may do a flush and replace it with the Toyota stuff when I buy a bit more.
I havent finished my comparisons between this one and the old one yet, but will have them soon.
