Synchromax is fully compatible with all types of friction materials and offers excellent corrosion and oxidation protection without affecting the soft metals commonly found in manual transmission synchronizers Review: I was skeptical this would make any difference...but it did. And the difference was impressive. I'm sold! - Got this to replace the MTX fluid in my 1998 Contour SVT, which I'm sure was still running the original fluid. The tranny felt like the former owner got a little too happy with the power shifts into 2nd--the synchro was really feeling like it was going to need replacement...something I really didn't want to tackle this year. Figured changing the fluid probably wouldn't help, but it was way over due anyway so I figured I'd just go ahead and do it. I did a quick search to see what type of fluid to use in it, and I kept seeing people recommend this... Now, I've been wrenching for more than 20 years, and I'm HIGHLY skeptical of anything that smells like "rebuild in a can", but I also try to keep an open mind...and frankly there were so many people recommending this I thought it was at least worth a try. Even if it didn't help at all, I figured it was probably no worse than the factory stuff. Had to be better than the almost 20 year old stuff in the car anyway lol. Anyway, I did a quick drain a replace, and took it out for a test drive. Frankly I was shocked at the difference...the improvement was immediate and very noticeable. The car shifted MUCH smoother, and I was very pleasantly surprised at how much quieter the car was. Does it shift like new? No. I can still feel the wear on the 2nd and 1st gear synchronizers...BUT, it's soooo much better than it was. So much so that I'm not worried about tearing into the tranny any time soon. I don't care if I get better gas mileage or anything else, the fact that it works so much better than it did would easily be worth twice or even three times what I paid. I'm very pragmatic when it comes to my repairs...I just want something that works. And this really does work. I'd recommend this to anyone doing a fluid change. Review: Car running smoother than I thought it could - I replaced the manual transmission fluid and differential oil in my 1998 BMW 323is, both of which hadn't been changed in at least 100,000 miles. This fluid in the transmission and RP Max Gear 75W-90 in the differential. I expected some improvement, but it runs much quieter and smoother than I thought it could. Sometimes it is like I nudge the shift and it sucks it into the gear I want. Really surprising how smooth it is. And my car is quieter even though I never thought it was noisy before. Now the main sound is the engine when accelerating and if I'm at cruising speed I just notice the quiet. Having said that, I should note that the existing transmission fluid was black and only about 1/4 to 1/3 full. There was some form of slow leak since the transmission was caked with dirt and oil yet I never had stains where I park my car. So I'm comparing to what was an obviously under-filled transmission with old fluid. The first 50 miles or so after replacing the oil the shifting was notchy and terrible and I was thinking I'd have to put something else in. I was also worried I'd fried it due to low fluid. But then one day it shifted smoother, and the next even smoother, until it was noticeably better than before. Now a week later I'm really impressed. Forgot to mention my transmission is one of the manual ones that take automatic transmission fluid (Getrag) and this is rated for that usage. Also I've noticed I have to go to 2nd gear much sooner now because the car gets to speed much quicker. So it seems to be responding better to the throttle as well. That seemed to have happened right after the change but I was babying the car due to the rough shifting so I only really accelerated normally a few days ago. Update 06/2012 - Several tanks of gas later and my MPG is higher. Really improved the highway MPG, and it just did 32.09 MPG, doing the relatively flat round trip Los Angeles to Palm Springs plus some other mainly highway driving. My car has been getting 23 to 24 for the last two years and maybe 25 to 26 before that. I've only hit 32 mpg once before in August 2009, and have had only 6 tanks of gas get over 30 mpg in the almost 12 years I've owned the car. Stop and go driving is just slightly higher than before though as the prior three tanks of gas were 23.03 mpg, 27.38 mpg, 24.99 mpg. Update 10/2012 - The mpg the last 3 tanks of start and stop local driving were all over 27 mpg. The EPA estimated mpg for my car was 17 city/ 25 highway. So it seems to be doing well given it has the original engine and transmission. ## Features - Greater wear protection - Smoother shifts - Excellent rust / corrosion protection - Reduces friction for more power ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B007SPM0RG | | Best Sellers Rank | #14,211 in Automotive ( See Top 100 in Automotive ) #54 in Transmission Fluids | | Brand | Royal Purple | | Brand Name | Royal Purple | | Container Type | Bottle | | Customer Reviews | 4.8 out of 5 stars 1,886 Reviews | | Included Components | 6 bottles of synchromax | | Item Form | Liquid | | Item Weight | 12 Pounds | | Liquid Volume | 6 Quarts | | Manufacturer | Royal Purple | | Material | Synthetic | | Model Number | 06512/01512 | | Number of Items | 6 | | Package Information | Bottle | | Part Number | ROYA01512-6PK | | Recommended Uses For Product | Transmission Fluid | | Specific Uses For Product | Manual Transmission, Transfer Case Lubrication | | UPC | 641330065125 | | Unit Count | 192.0 Fluid Ounces | | Viscosity | Low (relative to motor oils) | | Warranty Description | Please contact us if you experience any issues within 30 days of receipt. | ## Product Details - **Brand:** Royal Purple - **Item Weight:** 12 Pounds - **Liquid Volume:** 6 Quarts - **Material:** Synthetic - **Package Information:** Bottle ## Images ![Royal Purple 01512 Synchromax Manual Transmission Fluid - 1 Quart (Pack of 6) - Image 1](https://m.media-amazon.com/images/I/61UfgWHSAgL.jpg) ![Royal Purple 01512 Synchromax Manual Transmission Fluid - 1 Quart (Pack of 6) - Image 2](https://m.media-amazon.com/images/I/71fxUrjSejL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ I was skeptical this would make any difference...but it did.

This stuff is awesome, I've always liked Royal Purple oil, and have used several other products with good result. I decided to change out my gear box oil/ATF and wanted something that offered a little bit better protection for a manual gearbox, namely better protection for the "yellow metals" (like brass and Copper) that are used in manual transmissions. I was looking just to replace my existing fluid with something a little better, what I was NOT expecting was a significant change in performance... my gearbox now shifts MUCH more smoothly than before, it used to be a little hard to get into 2nd (you normally start in 2nd on a ZF5 when not rowing), especially if the gearbox was really cold. This thing is now as easy to shift as I imagine it was when it was BRAND NEW! It took about 50-100 miles for it to have this effect, but let me tell, it's awesome (and was entirely unexpected)! If you have a Ford with a ZF5 or ZF6, this is the right choice for your gearbox (oh, and transfer case too!) and although it's a little pricey, it's worth every penny! The 6 quart pack was enough to do both my transmission and transfer case with about a third of a bottle (12oz) left. ## Frequently Bought Together - Royal Purple 01512 Synchromax Manual Transmission Fluid - 1 Quart (Pack of 6) - Slippery Pete - Fluid Pump for Standard Quart Bottles - 8cc per Pump Stroke and 3rd Hand Adapter, Transfer Gear Oil, Transmission and Differential Fluid (28mm) - Royal Purple 01300 Set of 3 Max Gear 75W-90 Oil 1-Quart Bottles --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/21556501-royal-purple-01512-synchromax-manual-transmission-fluid-1-quart-pack](https://www.desertcart.kg/products/21556501-royal-purple-01512-synchromax-manual-transmission-fluid-1-quart-pack) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-06-02*
