New Transmission/Rebuild?

[smcosta90]

When I shift into 4th it grinds. If I pause a second in neutral it doesn't grind. So I figure my 4th gear synchros are going.

So my question is how much would a new transmission cost me?

I saw a "damaged" one for $ 1000, but can't find anywhere in the old threads what a new one costs.

A new transmission in my suburban cost $ 2900(installed) but thats an automatic and not a sports car.

Thanks

We have a brand new gen 3 one that would work I could sell you for less than retail and it is here on the shelf.

Call me for details,

SC before you think about taking your trans out, change the fluid in it and see if that helps. 75W-85 syn MOPAR #4874459 [4qts]

 

[Tom F&L GoR]

Pssst. It's 75W-85W. (85 and 85W is not the same.) Another reason not to use any old 75W-85 gear oil.

and why is chuck telling him to supercharge it first before he takes it out...... ?...

Cause the guy's name is SuperCharged (SC), can you imagine living with a name like that.

Interesting point Tom...noting that the NEW 8 quarts of Mopar Syn. Man. Trans. Lub. in my fluids cabinet are labeled as " 75W-85"...noting further that the 2006 owners manual says "Synthetic Manual Transmission Lubricant SAE 75W-85 (Castrol Syntorq LT 75W/85)".

Can you tell us from whence your second "W" comes...AND the differences between "75W-85" and "75W-85W", please??

Thanks.

I think the W stands for winter. Or cold. Which means the dual viscosity of that would be 75 cold, 85 cold.

I'm with you on that Steve... And yeah, throw those 8 qts away. They're defective!

Tom, how can this have 2 winter weights?

 

[Tom F&L GoR]

Because the W does not explicitly stand for winter... It is merely a designation for a particular viscosity range at a particular temperature range.

The "85" means it should be more than 11 cSt but less than 13.5 cSt at 100C.

The "85W" means it should be at least 11 cSt at 100C, but also meet a low temp viscosity of cP at -12C.

The 75W means is also flows at -40C, so this product is similar to a multigrade vs. a single grade.

Steve, I will have to find my larger image of a Castrol Syntorq label, but it says 75W-85W. Here is a way-small image.

These guys sell two quarts of relabeled product:
NV4500 Parts

Apparently it is also a GM product
Castrol Syntorq LT 75W-85W GL-4 (GM# 12346190)

SAE would have been smarter to choose "A" and "B" instead of "85" and "85W". And also that Mopar marketing guys didn't read the label when they rebranded the product.

We can always rebuild the transmission for you if it comes down to it, done quite few whether for upgrades or repair. It will certainly be a lot less than a replacement, and you get YOUR trans back.

Also note, until you make a move and fix it or find out the root cause, take it east on that gear. Every one of those grinding noises is like tossing money out the window. Blocker rings are cheap............. gears and sliders/hubs arent.

 

[Steve-Indy]

Thanks, Tom...I see what the second "W" means...noting that the quote concerning the wording on the labeling was from the 2006 Owners Manual recommnded fluid section and NOT a bottle of Syntorq itself.

Certainly the second "W" does NOT exist on my bottles of the Mopar stuff. I'm always ready to upgrade if they introduce a better fluid.

Thanks, again, and Happy New Year !!

I have been believe me I hate the sound of gears grinding.

Thanks to everone for their input.

This could turn into another "which tranny fluid?" thread...

I looked at the NV4500 transmission on-line and it is like a tractor-4x4 with PTO take-offs box. So is the fluid you have provided the link for - that works in the 4x4s and tractors - the same as the OEM Mopar fluid?

 

[dave6666]

OK Tom. You win. Not on the label having double "W" but it has the NV4500 right down in the corner. I'm using tractor fluid in my Viper.

You must be registered for see images

i dont care what anyone tells me...im always gonna listen to TOM when it comes to fuel,oil and lube.

 

[Tom F&L GoR]

Just being an anal engi-nerd.

The SAE viscosity grade designations are routinely butchered. For instance, there should always be a dash between the two numbers and it should always be preceeded by "SAE." But how many times do you see "SAE 10W40" or simply "10W-40"? I know, trivial.
