Manual Transmission Filler Plug and Gear Oil recommendations

I paid about $8 and a local Toyota dealership. They also sold me a crush washer for $2 and told me I could use it twice.

Well I got one of those fancy GPS MPH apps on my phone. According to it I am actually traveling at a rate of 5 mph slower than what the speedometer reads. So in fifth gear at 2100 rpm I am traveling at 45mph. Does that seem right?

Today I will be flushing the radiator/heating system. Going to do the 3 day flush. I picked up the expensive Asian automobile green radiator fluid.

Getting ready for a climbing trip to Joshua Tree next week and looking forward to gettin it on the open road!

Did you put the RP max gear in the diffs too or just the transmission?

At the time I could only buy enough RP for the transmission (the stores in my area did not have a lot in stock). So, I used Mobil 1 75w-90 gl-4. It cost something like 12.00$ a quart.

I think we are supposed to use hypoid 80w90 or straight 90w gear oil in the diffs. 75w90 is supposed to be for the tranny and transfer case only. Not sure if it makes a difference, but it might.

I think I will try the RP max gear as it is GL4/5 compatible and you had good results with it. Not sure what I will put in the diffs yet.

You are absolutely right. I bought several quarts 80w90. I just got confused. I used Mobil 1 in the diffs.

I ordered the RP max gear 75w90 for the tranny and transfer case.

For the diffs I got this stuff since it was 80w90. http://www.royalpurpleconsumer.com/p...ine-gear-lube/

Will report the performance and my experience when it get in the van.
