   Does anybody have any experience of a slipping Auto Gearbox?
My '89 2.1 MV auto seems to be suffering cross contamination of the ATF and Coolant: the ATF level drops and the Coolant looks to have a film on it.
I've read about 
fitting an External ATF Cooler kit instead of the stock NLA heatexchanger set up and I've found a pretty comprehensive kit - is 
this something DIYable on the driveway?
I also wonder whether I could/should renew the seals between ATF and Diff, even though all the seals were replaced a little while before Lockdown.

As a side note, I just recently fitted the excellent Brickwerks Stainless Coolant pipe to replace my rusty original, so I guess the coolant had to find somewhere else to leak into!!
