Hi all.
I have a 1.9 automatic t25 which lost all drive.the fluid is mud brown .i have changed the cooling block on the front of the gearbox and changed the fluid.went out today and did 12 miles and it stopped again .how can i get all the water out of it? thanks.

Thanks for the link its let me know what im up against.i do have a different cooler on it now and it will go for a while does this mean the gearbox is trashed or do i keep draining the transmission fluid untill all the water is out of the system?

Have you checked your water system.Is it contaminated with ATF fluid.

[flatnbroke]

Yes has a little oil in it.i have now accepted i need a new gearbox but having major probs finding one .really annoyed as only replaced it 3 weeks ago due to no reverse gear so now v deep in my pockets trying to find a box for her.

This bit is worrying.

The problem was that when the cooler did fail, it failed internally. When this happened, it allowed the two fluids (ATF and coolant) to mix. So, the transmission would be filled with coolant, and the cooling system got contaminated with ATF. The result is a ruined transmission ($2500) and a ruined cooling system ($3500

Change your oil coolers regular or it could be you too!!!!

should this be something all automatic owners should fit, every time i read something on here i start worrying about something new

Certainly somthing i will be getting when i get a replacement automatic box.

Just so you know,Jed and al's company campervanculture.com are sole importers of gowesty products,should you wish to order anything from them.I would consider changing to a gowesty ATF cooler,they are not cheap,but a darn sight cheaper than a new gearbox/engine.

Do these have a auto gearbox heat exchange built into the main coolant radiator? ...just a thought.

They connect to the gearbox the same as the original cooler.if I am reading your question right Martin.They dont connect directly to the radiator.

[California Dreamin]

I have no specific knowledge of T25 autos but I do know on some designs a heat exchange is built into the main radiator...not on these then?
