Last week i got my oil, transmission, rear diff, t-case fluid all changed. And now when I start the car up after leaving it over night or after work I can't get it into any gears with out having to either rev up to around 3500rpms or waiting to warmup 5+ mins. The shop used Diaqueen for the tranny. I never had this issue before the fluid change. Searched around for lockout issues but those threads mainly had to deal w/ high rpm lockouts. Any suggestions?

 

They didn't use the diaqueen fluid that is used in the rear diff & transfer case in your transmission did they? They are by far the same.

Since this issue started after the fluid change in your trans, something wasn't done right...

 

The oil is too high of weight when cold. It thins out when it gets warmer. That's why you can't get it into gear.

 

He's right, i suggest if you run 10w-30 switch down to 5w if it's cold where you live

 

He's talking about his trans not motor lol.

But yeah OP I have the same issue, alot of us do in fact.

When the weather was down in the 30's last time I had my car out shifting was such a pain. I'd have to skip 2nd for 10mins driving. I'm using diaqueen in the trans too.

 

I used to have this issue as well, my car would move in neutral, at least my VIII did, my IX is a good boy.

 

Just deal with it for now. The spring months are coming, then the summer. Wait a year before you change again. When winter comes back around the oil will have broken down some anyways and you may not have that big of a problem.

 

Go through the trouble shooting steps, bleed clutch line, adjust clutch pedal. As long as those are good and your clutch was installed properly, assuming you've done your clutch, just try to slowly work through the gears as it idles. Also, diaqueen is a syn-blend so it tends to get a little thicker when it's cold than a fully synthetic.

 

You could always run the famous Mitsubishi cocktail in your trans. I ran it all winter when I daily drove my Evo, never had a single issue even with 0* weather. I still use it, its good stuff.

Letting it warm up a few minutes is a good idea anyway. Allowing the motor to warm up means you are less likely to be pushing hot compressed air through a not-adequately warmed motor.
While your waiting for it to warm up to the minimum optimum operating temp, you can move the shifter around in neutral (without resting your hand/arm weight atop the shifter) and it'll have a measurable impact on viscosity.
I hope they used the correct Diaqueen in your trans as I also hope this isn't because your syncros are shot.

 

sounds to me like they may have put the diaqueen LSD oil in your trans..that's for the transfer case and rear diff.

 

Make sure you find out what they put into your transfer case.... if they put a fluid that is not supported then it will ruin your ring + pinion. But yeah, I had the same issue with the transmission not letting me shift, in fact i still do. There is a way to adjust the clutch pedal, you can search for it to see if that helps.

 

Ive got the same problem. Just wait until the car warms up
