Help. 8spd coolant lines

[seekAmanitah]

Did a motor swap over Thanksgiving break. Had my younger brother help me to get his feet wet in mechanic work. Anyways, we put the rubber hoses back on the transmission for the coolant circulation but somehow never got them clamped. Of course one started leaking after a day of driving and I can't get to it to clamp them.


There is a box on the driver side of the trans under where the lines connect. I started to remove it till I notice some trans fluid coming out. I tightened back up. It looks like if I took this box off I could get to the lines. Although I would loose fluid. Is the best route to take it off and just fill it up afterwards? Maybe just drain it altogether and fill it back up afterwards? Of there another way that is better?

That's the heater assembly,if you remove it there's a possibility it'll leak tranny fluid if you re-install it with-out replacing the O-rings. Go buy yourself some long flexible hose clamp pliars,and you should be able to get at the hoses on the top. You'd be better off putting a floorjack under the rear of the tranny and unbolting the transmission crossmember, then lower the floorjack to drop the tranny down a couple inches to gain more access to the hoses.I'd avoid pulling the heater assembly off,as you'll lose some fluid,which means you should go through the whole check fluid level procedure afterwards to check the fluid level in the transmission.

Long flexible house clamp pliers? I'll look them up. But what you are saying is it should be able to be put back on with the cooler box thing in place?

You might have to drop the tranny down if you can't get a pair of flexible hose clamp pliars on the clamps. It probably depends more on how tight an area you can get your hand into then anything,if you have big hands you might need to find somebody with small hands,lol.
When I say drop the tranny down,i'm not meaning remove it from the truck,i just mean putting a floorjack under the rear of the transmission,then unbolting the crossmember that it's bolted to,which will let you lower the rear of the transmission down with it still bolted to the engine,and that'll help gain you a little more clearance to get at the lines on the top of the heater.
