Has anybody ever tried to flush the transmission with kerosene? I want to try and flush it out since it has never been flushed out before. I changed out the fluid in there about a month ago. Before it was rough shifting but after the new fluid its getting better. One of the old mechanics here on base told me that he used to flush his transmissions out with Kerosene to clean all the metal shavings and gunk that would build up over the years. Its a manual by the way

flush it out with more atf? at our shop we actually have a flush machine, but if you are trying to get it as perfect as possible i would just keep draining and filling and it will eventually get there.

Don't do that. The "old mechanic" probably cleaned parts with gas also. Manuals don't take atf. With my 89 4.2 Ax15 I use 75W90 full synthetic gear oil and it never shifted better. I highly recommend switching to that. Don't ever put Kero, Gas or anything else in there.

Kerosene, as in home heating kerosene will eat the seals in your trans.

If you want to flush the system in that trans, drain it and refill it with a cheap motor oil, take it for a ride, shifting thru all the gears, then redrain and fill with 75w90 synthetic.

I use royal purple synthetic products in mine, but you can use whatever you choose.

Dont use the kerosene.

kerosene is also called #1 diesel,which is what it is..if you have a tremendous amount of gunk or shavings in it then you could fill it with kerosene or diesel and let it sit for a while and then drain it out..no one else on here will probably agree with that but it can clean it up some..there are a lot of tricks that old mechanics can tell you that worked good for them back before they had anything else that the new generation of mechanics will disagree with
