Heavy Duty Valve Body

Hi,
has anyone got any experience with the heavy duty valve bodies from Wholesale Automatic Transmissions in Melbourne? My 4 speed auto is overheating on steep grades, I changed the oil( as much as you can) and have a cooler on it? but the problem persists.

Are you looking to fit one as a solution or do you have one already? Either way this is unlikely to cause or relieve overheating. It is the transmission slipping or excessive torque convertor slip that causes overheating. When you say you changed the oil did you also flush the oil till it came out clean by disconnecting a cooler pipe?

Do a full flush and see how it goes. http://www.pradopoint.com/showthread...l=1#post492320

Were you towing when it overheats?

16 litres of WS later I had a nice clean transmission!
