trans cooler line exhaust clearance

[jks67ss396]

Guys,

Trying to button up the 5.3/4l60e into my 71. Im using the trailerblazer manifolds. the stock lines (from a 04 tahoe 4l60e) are half an inch from the exhaust manifold.

Is that enough clearance or should i take them out and bend them? What would be the minimum clearance?

Also, i noticed that these lines do wobble just a bit when installed in the trans.

They install with these little clips and just push on... Is that wobble normal? Do you guys have any play in yours?

thanks guys!

I could not get the stock lines to work with the trail blazer manifold or my custom cross member, so i used russell pro classic hose and routed them inside the frame rail. I also made a heat shield where they go over the top of the exhaust. The factory clips suck and they will wobble a bit. The second picture is the fuel lines over the exhaust. I could not find a picture of the tranny line side, but i am sure you get the picture.

I had the same issue with the stock cooler lines, so I got the trailblazer SS lines. they route differently to accomodate the SS manifolds.
wobble is normal, as long as it doesnt leak....

where did you get the trailblazer ss lines? got a part number?

thanks!

I don't have the part numbers handy. I got them off ebay after getting the numbers from gmpartsdirect.com. I'll see if I can find the numbers...

I ran braided lines tight to the pan and forward to my cooler under the rad. It has only a tiny but less clearance, but it avoids crossing over the exhaust at any point.

You can buy some thermal heat sleves to cover the trans line... Summit sells them. You may be able to find some NASCAR/IMCA left overs on eBay too....
