Maintenance selection on a budget

[Spec-Beast]

Hey all,

I'll be taking my 06 GT to Jackson, WY for work this summer and the closest shop is about 1 1/2 hours away. My local shop recommended the 60k service, but being 1400 that's out of my budget. With that being said I need to be selective on whats done. So I have a few questions that I know y'all will have some great answers for.

 

1) All my fluids under the hood look fine, but I would like to just change the diff fluid for piece of mind since I don't know when it was changed last.

A) Is this a straight forward

process?

B) Is there a people's choice

fluid?

C) From what I understand

changing the front diff also

changes trans fluid?

 

 

2) I've noticed some wear on the serpentine belt and AC belt, so definitely an area of concern.

 

A) How does one know when the

correct tension has been applied?

 

B) Is this an OEM only type of

replacement or is aftermarket the

goto?

 

 

 

I really appreciate anyone who took the time to read/resond. If you have any ideas besides the standard tire pressure,brakes etc please let me know. I've had terrible luck with used cars lately and would like to stay ahead of the curve.

5mt or 5eat ?

 

I use Motul Gear 300 https://www.amazon.com/Motul-105777-Transmission-1-Liter-Bottles/dp/B07XQJ7D26/ref=asc_df_B07XQJ7D26/?tag=hyprod-20&linkCode=df0&hvadid=416770300790&hvpos=&hvnetw=g&hvrand=606188773018914959&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9003205&hvtargid=pla-887355832984&psc=1&tag=&ref=&adgrpid=92859401446&hvpone=&hvptwo=&hvadid=416770300790&hvpos=&hvnetw=g&hvrand=606188773018914959&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9003205&hvtargid=pla-887355832984

 

For my 5mt and rear diff. It's not cheap, but its the best. tranny takes 3.8qt's rear diff .8qt. Fill the tranny slowly, I use my suction gun to push it into the fill tube. A new crush washer on the drain plug is a good idea too. Oh, remove the fill plug on the rear diff before you remove the drain plug, I learned that the hard way.

 

 

I use drive belts from the auto parts store.

 

There may be a DIY in that forum below.

 

We assume the timing belt has been replaced when it was 10 years old

 

You can ask "google" how to change fluid...

I think I'm gonna go with Schaeffers fluids across the board.

Which tranny?

With a manual, the transmission shares gear oil with the front diff.

With an automatic, the front diff is separate from the transmission for lube/fluid.

It's an 06 spec-b so it's a 5mt

Obviously $1400 is a lot, but these are old turbo cars. Expect a bill like that at least twice a year if you take it to a shop.

 

The rear diff oil isn't super hard to change. You'll want something to suck it out with. Whatever 75W-90 you can get from an auto parts store is fine. My shop used Valvoline. They use a big bottle and a tube that kinda reverse-feeds it against gravity. You could make do with a squeeze bottle and fill it up until fluid comes out. It'll be a gross color in there coming out!

 

On your 5MT, trans fluid is diff fluid for you, yes.

Belt deflection specs (I bought a belt deflection tool that you put on your finger years ago because I wanted to be more precise, but it seemed inaccurate and worthless)

rear diff - valvoline 75w-90 synthetic in a bag (for ease of use) (walmart and other parts stores should have it too) https://www.napaonline.com/en/p/VAL889785

front diff - red line 75w-90NS was my favorite. I used vinyl tubing attached to a funnel to fill through the dipstick hole, not sure if you can do that as easily with the turbos

Yep, the vinyl tube on my suction gun works well for both my cars. Suction gun works well to push new fluid in.

When you go to change or adjust your belts, make sure you loosen the bolt on the adjuster first otherwise you'll break it. Like many here, I found out the hard way. I replaced mine with a set from NAPA. As for lube, I used Royal Purple in my 5mt and rear diff. All these tasks are relatively easy to do and don't need any special tools other than a large Torx bit to remove the trans drain plug.

[Max Capacity]

Isn't that a 70 torx for that drain plug ?
