Thread: auto got hot, is it now wrecked?

I think he was pretty clear.
If the 4HP24 that you have is from a P38, then the transfer case on a P38 is different, as the outputs on a P38 are on the left side not the right side as in a D2.
So the mounting points for the transfer are wrong/flipped.
AFAIK the discussion UK is about P38 to P38 where the transfer mountings are the same.

If that were the case Phillip, then you couldn't fit a 24 to a d2 unless you got one from a NAS d2. Roarin8 got his from a p38a.
Perhaps the OP should send Roarin8 a PM

i did send roarin8 a pm. he didn't reply.

To clarify, wont an LT230 go on to the back of the 4HP24?

Sorry for coming onto this thread so late.

I find that one of the problems with the D2 cooler is that there is basically only convection drawing air through the element. This is because the lack of a direct connection requiring airflow caused by engine fan shroud which pulls air through the engine radiator, the resistance of the element itself and its position reduce the airflow through it from the forward motion of the vehicle.

In relation to the transmission cooler, an additional capacity cooler is a good idea, however placing it in front of the radiator will decrease the efficiency of the engine cooling. You may also want to install an engine oil cooler to compensate. Having an electric fan on the cooler can be a significant benefit, particularly if thermostatically controlled.

You may also want to consider installing a transmission temp guage. I advocate this because by the time the indicator lamp comes on, the damage may already be present. By monitoring the guage you can adjust your driving style to achieve the best transmission temps. e.g. I have engine and transmission coolers plus engine oil and transmission temp guages on my RRc with ZF-4HP22 transmission. On a journey with a tri-axle 4 tonne plant trailer loaded with an SIIB forward control and spare transmissions. I had to drive up Mt Victoria west of Sydney. Monitoring the transmission temp I was achieving the best temp Vs speed in 3rd but engine oil and transmission were in high normal range. As I started clumbing the mountain both transmission and engine oil temps were in the high-extreme range so I decided to pull over and run the engine in park and watch the transmission temp fall before moving. Just as I was pulling up the warning lamp came on.

Had I only had the warning lamp I wouldn't have been planning to pull over and may have done transmission in only a few more metres.

As it was I had to stop twice more on the climb but got to the top of the mountain without ruining the transmission, I did get the burning smell near the top of the mountain so changed the oil on my return to Sydney and am still running on the same transmission 5 years later.
