Can someone confirm my part numbers, it's a 700r4 matted to a 3:73 ring and pinion with factory 245/50/16

I have drive gear grey 8642620
Driven dark grey 9780470
Sleeve driven gear 25007339

I've been driving this car putting extra miles on it for no reason but procrastination

Thanks

 

Recently got a fresh rebuild on my 700r4. I asked the shop to replace the drive and driven gears for the speedo but they never did.

Do I need to drop the tail housing?

Is there fluid inside this housing?

I'm assuming yes to both of these questions.

Really wish the shop replaced these gears as I even provided part numbers

 

There is a small amount of fluid in the tail housing.
Not sure on your part number I think it should be 8 digits for 89-92.

15 / 44 tooth counts.

 

Thanks for the confirmation on the 15/44

Just wondering if i need 3 different parts:
1. 44 tooth
2. 15 tooth
3. Sleeve driven gear 25007339 ? I made this post awhile back and can't find info what pointed me to this part. What does it do?

Can I just use the 15/44?

 

Iirc the vss covers 40-45 driven gears.
gm 10456088 or 10456089, standard motors sc12 34 to 39 tooth driven gear and sc13 40 to 45 tooth driven gear.

 

So chances are if I'm doing a basic swap from 3:23 to 3:73 I shouldn't need this part?

 

Assuming you have a blue 38 you just need the driven gear.

 

Thanks for all the replys. I've ordered the 15/44.

 

9780470 is for speedometer cable drive, not VSS.

 

Here is a 44 tooth for electric Speedo :
