We have fitted the PWR 280 x 255 x 19mm trans cooler with 3/8” barb connectors to 4 of our ZF cars with no issues at all. FG G6ET, FG GTE 335, BF2 Ghia, SY AWD turbo territory. 2 of them have trans temp gauges fitted and they sit around 55 degrees C or less when cruising, and the GTE has maxed at 80 degrees going slow in summer. (Normal max temp for them with stock water cooler would be same as engine operating temp with is in the 90 degrees range. Heat is the biggest killer of auto boxes, so the “cooler” (relative term - 55 degrees is still hot and would burn your skin) you can run them, the longer they last.



You will need the PWR cooler at around $180, 3m of 3/8 trans cooler hose ($30 - $50) and ZF specific barb or AN to barb fittings (Aeroflow do some) around $80 for 2.

You can then remove the lines from the stock block mounted cooler on the barras, and join the hoses with a section of suitable hose (13mm I think). We left the block mounted cooler on the territory and just cut the plastic line to it - will fit some 13mm hose to the cut ends at some stage just to make it look neat.
