I recently used this sealant during a transmission pan drop on my truck. 2 Weeks later and no leaks what so ever. Easy to apply, fast curing, highly recommended.

Great products but
Great product and good price but please stop sending survey request to me every other day! I bought auto parts from you, not a mercedes with road side assistance! Your repeated request for me to take an 8 minute survey actually tempts me to use another store for future shopping.

Can you use this as an oil seal on a transmission axel oil seal? Or as a patch to keep from having to pull the axel shaft that your budy put in and now has a slow leak? Not sure what the difference is between driver and passenger side but the passenger side is not sealed completely. But the driverside is perfectly fine. Or should I just pull the axel shaft again considering all the parts are new form the axels shafts,wheel hubs,rotars,break,pads,and I rebuildt the calibers and replaced both transmission seals as the drivers side was leaking at the time I removed both axel shafts?

Hi Matthew, I'm glad to assist you! This Permatex Ultra Black Maximum Oil Resistance RTV Silicone Gasket Maker - Part # 82180/82150 is recommended for use on transmission pans, oil pans, timing covers, and differential covers. However, this should be used with an oil seal where oil can come in contact with the gaskets, to minimize chances of leakages from the gasket area, transmission, axles, engine oil pan, and final drives, etc. The driver's side and passenger side are always based on perspective when sitting in the car, so the left side is the driver's side, whereas the right side is on the passenger side. For more information, you may contact Permatex directly at 1-877-376-2839 and one of their Parts Pros will gladly assist you with any questions or concerns you may have.
Would this work to use as oil pan gasket?
