What are the best and cleanest looking options for the re-connection of the plastic transmission line fittings to the existing transmission cooling lines for an 88GT w/auto to begin with, when installing my 3800SC w/4t65EHD. Any pics? part numbers, etc. advice is what I'm looking for. Curtis

There are some "4t80e" fittings on summit.

I have used cut stock lines with hoses smashed over them for 10 years and counting..... you could also throw compression fittings on cut stock lines.

Below is a list of fittings and braided hose I recently bought from Jeg's to plumb a 4T65-E trans up to Fiero trans cooler lines.



The weld-on fittings were purchased so I could TIG weld them onto an existing trans cooler we already had. You can buy external trans coolers that already have threaded fittings on them so you don't need to weld anything.

The 5/16" inverted Flare (1/2"-20 thread) to -6 AN "brake" adapters were used so we could get a "bullet proof" connection between the hard (steel) lines on the car and the -6 braided hose. The stock mild steel and even the stainless steel trans cooler lines (sold by the Fiero Store) can be double-flared at the transmission side easily enough with a good flaring tool.

Upon advice from my trans builder (www.tripleedgeperformance.com), I've been removing the stock Fiero radiator from the trans fluid cooling loop and only running an external cooler of at least 26,000 GVW capacity mounted out in front of the A/C condenser.

I no longer use rubber cooler hose and clamps on any of the swaps I do nor am I a fan of compression fittings. AN 37 deg flares or double (inverted) flares are all I use and recommend when making connections to hard lines.

The stock Fiero mild steel (and also the Fiero Store stainless) trans cooler hard lines are 5/16" diameter which is a -5 size in AN. Finding -5 AN fittings is difficult and expensive hence the reason for the adapters from inverted flare to -6.

Talk to Dave @ Triple Edge for the special fittings to screw into the transmission itself so there is a -6 AN hookup directly on the trans.
