Truck#1 Posted July 28, 2007 Share Posted July 28, 2007 You guys have been great. I've learned a load of stuff from you guys. So one more question......I've been driving a 95 CH613 w/fuller 10 speed......it has no trans cooler. I've bought a 98 CH with a fuller 10 speed...the trans cooler lines have been disconnected (cut). I want to replace them. My question is this...how important are the cooler lines??? Again thanks for your help.Rob W.

MidniteMechanic Posted July 28, 2007 Share Posted July 28, 2007 First off check why the lines are disconnected. Does the cooler leak? Engines over 400 hp require them. And with todays aerodynamics theres not enough airflow under the truck to cool the transmission without a cooler.

Truck#1 Posted July 28, 2007 Author Share Posted July 28, 2007 The last owner said the last set of cooler lines were rubbing against the spring shackles and started to leak. I have a 427 ...but i was going to replace them anyway. thanks for the info Quote Link to comment https://www.bigmacktrucks.com/topic/2700-now-a-trans-question/#findComment-13164 Share on other sites More sharing options...
MidniteMechanic Posted July 28, 2007 Share Posted July 28, 2007 By the way you'll need to recheck the oil level after you hookup the cooler again and drive the truck.

Truck#1 Posted July 29, 2007 Author Share Posted July 29, 2007 Does it matter which way the oil flows through the cooler? I know the trans is labeled...oil out (I think). Do the lines purges themselves after everything is hooked back up and running???

MidniteMechanic Posted July 30, 2007 Share Posted July 30, 2007 No it doesn't matter which way the oil flows. Yes everything will self purge when you drive it. Depending on the length of the lines and size of cooler, it will only take a few extra pints of oil. Extra oil helps cool to!
