Fluids?

[clayton_n]

Im am fixing to do a complete fluid change on my truck. Oil, Tranny, front and rear diff. I am planning on using royal purple and i have to order it. I dont know how much trans.fluid or Diff oil it will take. Im sure i could research a lil harder and find this somewhere but it just seemed easier to ask. Also if anyone has any opinons on weather this royal purple is actually worth the price, please feel free to let me know.

 

Thanks

Not sure what vehicle. For the diffs, get 3 qts for the rear and 2 for the front. Oil should be 6 qts. Tranny depends on whether you are dropping the pan or flushing. If just dropping the pan, 5 or perhaps 6 should cover it. If flushing, a case, possibly a few more depending on how you flush.

 

I am personally not a fan of RP but plenty of others will swear by it. I'm of the opinion any quality brand name should be good enough. I'm a fan of Mobil 1 but recently tried Amsoil trying to get longer changes (with oil analysis).

[D&SYukonDenali]

How many miles do you have? Has the transmission oil been changed before?

 

I ask because I personally would not change the fluid brand in the transmission from the OEM brand if it has been in the trans for an extended period of time (e.g. 100k+ miles). My fear is that "crap" gets built up in areas of the trans when the fluid has been in there a while and if new fluid type is introduced, with different kinds/concentrations of detergents, with can free large chucks of the "crap" build up and cause problems or transmission failure.

 

Just my opinion though.

[clayton_n]

Sorry, I didn't even notice that i forgot to say what kind of vehicle. Its an 2003 z71 5.3L. Im pretty sure it has a 10 bolt rear end. It does have one of those g80 factory Lockers in the rear. as far as the front end goes....No clue.

 

Also, when it comes to my oil, I always use mobil1 synthetic. as far as the Diffs and tranny goes...open to suggestions. I just heard that RP was the best. What is recomended for the tranny at 100k miles?, flush or pan drop?..can i flush it myself (does it require special tools?) or do i need to take it somewhere?

[D&SYukonDenali]

I would never do a flush. I would just drain, drop the pan, change filter, clean off the magnet (if it has one), and top off with the same brand as OEM or recommended equivalent.

[Bish]

I agree you should stick with Dexron in the trans. My trans vbuilder won't warranty his work if you run synthetic. I've used Mobil1 in the diffs.

Remember that transmission oil, whether it be synthetic or conventional, has to meet the Dextron standards. Which means that if your trans man won't warranty his work because you used synthetic oil, he's not much of a trans man. Dextron is not a brand name but a set of standards for transmission oil. Synthetic oil will hold up longer and lubricate transmission parts better, leading to longer transmission life. It also tends to help lower transmission temperatures, also leading to longer transmission life.

Could not have said it better,

 

Also the new Dextron V1 that GM puts in transmission now is simi synthetic.

The newer GM diff fluid (people have been calling it grape juice because of its smell I believe) is also very good. I believe it is also a simi synthetic or full synthetic.

[C & A s Dad]

I do not want to beat up on RP gear oil but I did some research before changing mine. I ended up with Amsoil simply because the Amsoil Severe Service gear oil produced better specs than the RP. If you contact Amsoil they will send you a copy of a comparison test of all of the top brands of gear oil. It was surprising to me, but the OE GM "grape juice" out performed RP in some categories if I remember correctly. Overall, the Amsoil tested with better results. It was not superior in every category tested, but was in most and very respectable in those areas where it was not at the top.

 

I also have Amsoil in my engine and trans.

I politely beg to differ. First, my trans man is Finish Line Transmissions and he is well know and one of the better performance builders in the country. Second, Amsoil and Mobil1 trans fluid (synthetics) claim to meet all specs. A trans fluid CANNOT meet Dexron III and VI and Mercom and anything else because they are different specs. Amsoil claims to work for both Dexron III and VI yet the viscosity spec is different. Same for Mercom and ATF+++. Read the spec for trans fluid for all manufacturers and explain how one fluid can meet all specs? Also, if you look at the Dexron VI spec it is actually a synthetic blend now instead of the dino for Dexron III.

[clayton_n]

WOW. Ive been doing some reading on this AMSOil stuff. It seems pretty awesome. I could really enjoy only changing my engine oil every 25000 miles! It really works that good? well I was just gonna run Mobil 1 in my engine but I think im sold on this AMSOil. I will probably do 1 more Mobil 1 change in my engine while I get the AMSoil for the Diffs and tranny. otherwise it will cost me a small fortune to buy Amsoil oil, oil filter, trans fluid, trans filter, and front and rear gear oil.

Really?

 

Here is what GM (the people the invented the trans and fluid) say about it:

 

General Motors DEXRON^®-VI Global Service-Fill Specification

 

 

 

 

During early 2005 General Motors released a newly developed automatic transmission fluid (ATF) for the factory fill of all GM Powertrain stepped gear automatic transmissions. The new fluid provides significantly improved performance in terms of friction durability, viscosity stability, aeration and foam control and oxidation resistance. In addition, the fluid has the potential to enable improved fuel economy and extended drain intervals. Since the performance of the new fluid far exceeded that of the DEXRON^®-III service-fill fluids available at the time it became necessary to upgrade the DEXRON^® service-fill specification in order to ensure that similar fluids were available in the market for service situations. This latest upgrade to the service- fill specification is designated DEXRON^®-VI.

 

Since General Motors introduced the first ATF service-fill specification in 1949 it has been periodically necessary to upgrade the specification. This upgrading process ensures that available service fill fluids are of an appropriate quality for use in transmissions that have been designed around the factory fill fluid performance. It should be noted that, as with previous upgrades, DEXRON^®-VI fluids are designed to be backward compatible with earlier transmission hardware. More importantly, earlier type fluids are not forward compatible with transmission hardware that was designed to use DEXRON^®-VI fluid, i.e. DEXRON^®-III is not compatible with the most recently designed transmissions, and the use of these earlier type fluids could result in transmission damage. All current calibrations and certification tests are now conducted with DEXRON^®-VI ATF. DEXRON^®-III fluids should not be used for these applications where the owners manual recommends the use of DEXRON^®-VI. GM does not license or support obsolete ATF specifications or the use of fluids that are being marketed against cancelled specifications.

 

All DEXRON^®-III licenses expire at the end of 2006 and will not be renewed. Beyond that date GM will only support the use of DEXRON^®-VI fluids for use in Hydra-Matic transmissions. Fluids sold in the market after that date bearing claims such as “suitable for use in DEXRON^®-III applications” or similar wording should be avoided. DEXRON^®-VI licensed fluids are fully backward compatible and can be used in all applications covered by earlier GM ATF specifications.

 

The use of unlicensed fluids and/or non GM approved aftermarket additives may prove detrimental to transmission performance and void warranty coverage.

 

There is a published list of GM-approved brands of DEXRON^®-VI (see page two of this release). This list represents the companies who have conducted the appropriate testing and received GM approval. Company name, license number, and brand name are shown. This list will be updated on a regular basis as more approved products are added.

Didn't see any fully synthetic or Mobil1 or Amsoil on that list. I could be wrong but all those are semi-synthetic blends just like oem Dexron VI. I was speaking of full synthetics not being good and not supported by my builder.

 

Am I missing something?

[dlstewart01]

I do not want to beat up on RP gear oil but I did some research before changing mine. I ended up with Amsoil simply because the Amsoil Severe Service gear oil produced better specs than the RP.

I also have Amsoil in my engine and trans.

 

 

Who had these test conducted, and who paid for them???
