High Tech Transmission Lines.
We have assembled this P.T.F.E. lined stainless steel braided hose kit for the 4L80E and 4L85E GM transmissions.
The kit contains all the components to connect your transmission to your choice of cooler using -6AN hose and fittings.
The teflon liner is inert to any type of automotive chemical so it won't leak, plus it is covered in a stainless steel braid for additional abrasion protection.
The hose ends have been designed by Fragola to be reusable and also swivel to allow for easy positioning.
We provide black anodized aluminum adapter fittings for the front and rear cooler connections on your transmission.
These replace the stock fittings perfectly with 9/16"-18 x -6 AN straight threads with a o-ring seal.
We purposely do not include the transmission cooler adapter fittings due to the various types of coolers offered by the aftermarket. You will need to purchase the correct -6AN male to whatever inlet thread your cooler requires.
NOTE: in 2009 GM started using a 9/16"-18 threaded fitting in place of the 1/4" fittings on some crate and performance transmissions.
On top of this, they have also moved the return fitting to the back of the case to better lube the center bearing.
It is imperative that you check the thread diameter on the rear port as it could be 9/16-18 or 1/4"NPS.
This fitting will have the extended tube which must be used to prevent erratic shifting.
If you have the 1/4" NPS fittings use our kit P/N: LP-526 instead.
