OEM G52 did not shear down at all in 43,000 miles of use: So, I went to the dealer this morning, bought a liter of G52, then drove to my local CAT fluid analysis lab and watched as he tested its viscosity right in front of me.Ħ.3 = OEM G52 (part numbers G052726A2 / G05272601) My thinking was that either the OEM oil sheared way down OR the OEM fluid started out much lighter than the 75w-90 oils that many of us are commonly replacing G52 with. I had the lab perform a VOA on the Motul Gear 300 I put in and its = 14.0. The CAT lab ran the viscosity test twice because I listed the oil as being a 75w-90 - which G52 clearly is not. of the factory fill (G52) in my 2004 Golf TDI 5-speed after 43,000 miles was 6.4. Obviously, based upon your success w/ Redline MT-90 in this transmission, Redline MTL should work fine.Īnd yes, I would suggest draining the MT-90 out ASAP and replacing it with something much thinner, as the transmission was designed to tolerate such a heavy lubricant. The correct replacement fluid for this transmission should’ve been Molakule’s MTFGlide, the Genuine VW fluid, or possibly Redline MTL, even though it’s thicker. The decreased shifting performance may’ve been a result of the friction modifiers wearing out and may’ve been unrelated to the slight or no shearing of the fluid. Can a 75w90 possibly shear to 14.5 cst, when 75w90 lubricants are extremely shear stable? Very unlikely. Obviously, this report shows that the original factory fill was the latter, not the former! Some come with a GL-4 75w90, while others come with a lubricant having an automatic transmission fluid like viscosity. Not all VWs come filled with the same 75w90 manual transmission lube! Many customers indicate feeling a true connection to their vehicle once the factory softness is removed.We go through this silly discussion every time someone posts a VW Manual Transmission Analysis. The mounts do increase in cabin vibrations and noise, however VWR has refined the mounts to offer only enough stiffness as required without sacrificing comfort. Such failures can lead damaged engine and driveline components due to shifts under load.Įngine and Transmission Mounts offer a true upgrade for those running the VWR Subframe Mount alone, and all but eliminate "Wheel Hop" on even the heaviest of modified vehicles. In doing so, soft compounds are used which introduce engine and transmission movement which can decrease stiffness and result in failure. The subframe mount alone is a perfect starting point for anyone looking to increase performance without adding much vibration or noise.įactory engine and transmission mounts offer a heavy compromise between performance and comfort to satisfy an extremely wide range of customers. This mount fully replaces the factory part and does so without attempting to bandaid the issue with small plastic or rubber inserts. "Wheel Hop" is greatly minimized with this modification alone. The subframe mount offers a significant reduction in movement experienced on and off throttle, between gear shifts and under acceleration. Many companies make the mistake of labeling extremely harsh and noisy engine, transmission and subframe mounts as performance products for the street, but in doing so they heavily sacrifice the driving experience without increasing performance.ĭevelopment underwent several updates and revisions before perfecting a balance between comfort and control. ![]() Vehicles developed for racing only applications differ heavily from those driven on the street and as such requirements between both are often not directly shared. Initially VWR engineered mounts for use in the UK Volkswagen Racing Cup and developed a solution great for race cars, but lacked refinement needed on the street. Racingline spent a considerable time engineering these mounts for daily driven vehicles and as such has developed a product that's suitable for mild to heavily modified vehicles. By tightening up engine and transmission movement, drivers will instantly feel the differences the second they pull away. Racingline Engine Mounts are designed to decrease engine and transmission movement to facilitate proper transfer of power to the road.
