Transmission fluid in my engine coolant. The steps I have taken are as follows. Step one buy new radiator (OEM -NOS) from gary@jagbits.com

2. Drain and flush old rad for re-core.
3. Install new rad. Flush system until clear.
4. Install new upper and lower rad hoses. Fill rad.
5. Flush and drain Transmission.
Replace filter/gasket and refill rad.
6..Replace transmission if any damage/poor shifting is evident.

Please let me know if anybody has any experience with this problem and any recommendations that they took.

 

If its only trans fluid in the cooolat, and not the other way round, the trans is probably OK.

I would be changing ALL the coolant hoses, so lots of fun.

Then dismantle the banjo breather arrangement on the top of the RH radiator tank, and flush the goo from thoses small pipes that run to the LH side.

A new radiator, maybe. I remove the trans (and power steer when applicable) from the radiator, and install a trans cooler out the front, then it simply cannot happen again, and the cooling system will work better.

Plug the 2 fitting holes in the old radiator to stop coolant loss in YOUR case (coz ya got a split trans cooler anyhow), and carry on.

The heater core will also need flushing, both directions.

None of my Jags have ever kept the trans cooler or p/steer cooler in the radiator. I by-pass that nonsense when I first get the car, never, ever, had an issue.

 

My rad guy mentioned the separate trans cooler. No powersteeing stage in the 95-96 rads. Probably why I couldn't find one under a grand. They only made them for 2 years. I will post results.

 

yeah, you can buy simple trans coolers that just mount in the radiator setup like an oil cooler to eliminate the problem. The issue with this situation is that after shutdown, the trans fluid is no longer pressurized and the coolant is, so the coolant always finds its way into the trans. If it is a pin-hole leak, maybe there was just a little exchange and no damage was done. Good luck, the turbo400 is a very sturdily built piece of junk, so it is probably fine.
