Transmission Filter

You would have to go the the filter manufacturers website to find the specs. Most likely you will need to use their technical service support to find out what you want. Personally I think fluid changes are more important than filter quality in automatic transmissions.

All the transmission filters I have seen are pretty sketchy. Most are little more than screens to keep out larger particles. If filtration is important to you you might want to add an aftermarket spin on oil filter inline to the transmission cooler. Subaru used spin on oil filters on their automatics which I thought was a great idea.

Thank you. I agree that "the vast majority of filters a little more than a screen". Because of today's extreme technology in both fuel systems and automatic transmissions, superior filters (good synthetic fluids) are more important than ever before. For example in a fuel system: many fuel injectors are operating with 10,000 β or higher, (β4≥10000) and lubricant filtration 4μm - 10μm with the same Beta Rating β efficiency rating, (β5≥20000). And it is very hard to get that kind of information.

For example in a fuel system: many injectors today are operating with 10,000 β or higher, (β4≥10000) and LUBRICANT filtration with 4μm - 10μm particulate screening, with the roughly the same Beta Rating β efficiency rating, (β5≥20000). And it is very hard to get that kind of information from the manufacturers... thus was hoping someone may have found a source to reference?
