Trans fluid change question?

[chevyok06]

So tomorrow i am changing the fluid in my 2012 sonic 1.4 6 speed mt. I have read that the trans really likes about 2.5 qts. I bought a gallon of redline which doesn't have markings on the side of the jug. So my question is, How much does it take to get it to start draining out of the fluid check plug hole? Believe plug 1? Also once it reaches that point About how much should i add to get it to the preferred level? Thanks in advace!

When I changed mine recently I simply drained and filled. Only 1.6q came out of mine when I drained it and I put in 2.5q RL MT-90.

Make sure you clean the surfaces first before pulling the plugs.
* A long neck funnel is helpful and need a torq wrench.
* I did not have to remove the fender liner or plastic skid covers.

This link should help, you need those torq spec's for the fill and drain plugs. I also just reused the original plugs.

How do you like the redline Tormach?

So far, shifting feel alot better. Cold morning 0° to 20°starter are alot smoother. Overall very happy with the RL I got and will def be using it again.

This spring I have to check what m32 trans casing I have, pre cooling channel or post. I'm not having an issues or grinding at all but I want to be prepared for the future. If it's the pre cooling channel, those are prone to bearing failure, so I want to have a new trans and clutch lined up.

2012+ have the new case cover design, so all Sonics have it. If you get a backup, go for a 2013+ they have a few other redesigned parts.

I just changed my gear oil with Royal Purple 75w90 synthetic and now its leaking out the case cover. Is yours holding tight?
I'll swap in for Lucas or Valvoline next time and may just have to change gear oil with every oil change :/ My tans is getting worn out.

I figured it would be the redesigned casing but better to check and make sure.

68k miles total on the car and about 8k with the RL MT-90 atm and no leaks so far. I will check that out as well to be sure. My next change will be at 85k - 90k total miles or sooner if i update the clutch.

15-20k miles is a good amount with these trans. I spoke on the phone with Warren at WG Motorworks in the UK when I was looking for M32 rebuild parts, he told me in 2010-2012 GM was sending out M32's with cheaper bearings than older models with Timken.

2013+ GM moved back to Timken when the case cover was redesigned and added a few other things. He's extremely knowledgeable, give him a call to see the best newer year model for a used M32.

The case cover has a sealant but doesn't look like a regular high temp RTV used on most manual transmissions, so I've been hesitant to pull the cover and reseal it. When I drained the fluid maybe a quart came out, pretty sure the leaking cover has been there a while and is now worse with more fluid in the trans, it gets really hot. Going to call Warren next week for his recommended sealant for the cover.

I've been to that site, alot of good info. Have another euro site with info on the m32 on my work computer. Hopefully it's an easy fix for the leaking issue.

Speaking of covers, y'all know the torque specs for the diff cover?

There's a thread somewhere here. Try a Google search, i think its titled something like "Useful Torque Specs"
