Transmission Flush for 1999 v6 5spd

Planning on doing a full fluid flush on my 1999 tacoma. Its a 4wd v6 5 spd transmission. All the threads I've read on here is about automatic transmissions an i was wondering if there is a difference in the two. My truck has 132k on it an i bought it from the original owner a year ago an I'm not too sure if it had a regular flush at its 30k intervals. I'm no expert but if its something i can do my self that is not too complicsted im willing to give it a try to save some $$. There is some skeptical saying a full flush is not worth doing because i could ruin the transmission but those stated for AT is that true for MT as well? Can anybody give me some advice?? Thanks!

 

The manual transmission fluid is just gear oil. Your owner's manual will tell you weight, specification, and quantity. There will be a fill plug and a drain plug on your transmission. Open the fill plug (to make sure it's not stuck and so the draining doesn't glug), then open the drain plug. It'll just take a couple of minutes to drain it all out. Then replace the drain plug and fill it back up. Filling is easier with a pump that screws onto the oil bottle. You can get it all at your local parts store.

No danger to a manual transmission doing this.

 

Change the MT gear oil at will, no worries with those as there are with the AT.

Recommended oil here on TW is Redline MT-90. Did the change on my 99 with over 315k miles on it and the transmission shifts great.

 

There is a bunch of W 59 information lower in this link .

One of the benefits of a manual trans, there's no need to do a flush...just drain it and fill her up.

 

The process is similar to doing a fluid change on your differential which is nice to know if you haven't done that before.

Great posts here already, but heres a video that shows how to change the trans fluid on a manual taco as reference:

damaging a transmission after a flush is a myth. If it fails after a flush, it's because it was due to fail anyway

oil for manual transmission:

$30 75w-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75w-90

 

Just warm the fluid up and dump it out Redline MT-90 in my 98 V6 5 speed as well. Shifts fantastic!

 

Right on thanks for all the info guys! Will be ordering some redline mt-90 an as soon as it comes in i will change out the fluid.
