Thread: Subway's GT: Time to close my legs, it smells everywhere

Let me explain trans fluid to you.

It's a detergent based oil, much like your engine oil. It is intended to be changed about every 30K miles, much like your engine oil except less frequently. Within that 30K time frame the filter does it's job and the oil gets dirty etc, much like your engine oil except on a different frequency.

Do you change your engine oil? Because that's all a transmission service is doing.


There is a lot of myth about people doing a transmission service (pan drop and filter change) and it killing the trans. Reality is that they had an issue and thought, maybe it's time to perform the overdue service. Unfortunately..that was not the case, the trans had an issue and doing a fluid change didn't help it and the dirty fluid may have masked the issue a bit. I openly tell people if they are having transmission issues to save and replace/rebuild. instead of doing the service. Most of the time, the trans is on borrowed time.

So basically you're saying to not touch the transmission and just save for a new one? I think it's internal damage because the car will slip going into second at around 4kRPM WHEN WARM, but going into third, I had it at almost 5kRPM, and it shifted perfectly normal.....

Didn't know this I thought I'd get 50k out of it guess I'll add this to my upcoming service then!
