This is a question I have been looking to ask for some time and now I see the other post that just came up by RZinKY which prompted me to ask this. First I have a question, what is the thing on the pass side that the tranny lines go to? I am guessing it works with the coolant to warm/cool the tranny fluid. Do I need to keep this in the system?

Now my idea. I have used the big B&M cooler from Summit on a few race oriented cars in the past with very good luck. My idea since these stock lines are so prone to leakage is to run this cooler instead of the factory front mounted cooler and soft lines all the way from the tranny. I would get good lines, either USCG approved or a 'strong' fuel line. I can run them where I want and keep them out of harms way. The pressure will be no problem but will this work for the temperatures these run at when under stress? Has anyone else done this? After I do the Goerand in the next couple weeks I wanted to go through the whole system at that time. Even though Dave says not to worry about the stock cooler being contaminated I am a little worried.

Any opinions?

 

I don't know why I didn't think of hydraulic line, that seams like an obvious answer considering a tranny is generally a hydraulic system. My question then is are you guys using crimped end style hydraulic line or just barbed fittings and raw line. Any good source? You would think I could come up with this since I work for a company that supplies the majority of the tube in the US that goes into hydraulic/pneumatic cylinders. I'll have to talk to some of my customers tomorrow.

What size lines am I looking for? 1/2?

 

Quite a few folks have switched to 3/8" hydraulic hose rather than pay the price for hard lines. Best way is to remove the stock lines and take them to a shop that can crimp on the right fittings for you.
The tranny to engine coolant cooler you saw is a good thing to have if you live in the north. Not only does it make your ATF harder to exceed coolant temp it will also keep your fluid warm in sub zero weather.

 

1/2 inch OD is what came stock. KD

 

I did away with all the factory stuff. I have stainless braid and a large fan cooled cooler mounted up under the bed and I also put on a spin on filter inline. Have about 400 in all the parts and fancy anodized fittings.. Every fitting is either pipe or flared AN fittings.. NO LEAKS HERE!!!

 

Called 5 local dealers today, none had the lines in stock. I was priced around 200.00 to order. having trouble paying 200.00 for 10.00 worth of tubing. I ran across a post with good info and Pic's 4/18/06 think I'll give it a try.

1 dealer said they installed 6 different auto trans in 1995 and i need the # off the tag on the bell housing. Mine has no tag where would i find trans #'s
