Painting Trans ???????? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

BP68 · 01-21-2007, 09:50 PM

Hey all. I have a 700R4 trans in my 68 project truck. Running a 4 row factory style radiator with built in trans cooler and dual electric fans.

The trans case looks cruddy after all the paint and chrome went on the engine and frame.

I want to paint it. I have heard this can hinder heat dissipation. Does anyone on here have a painted trans? Any probs? And advice?

I guess that I can see the logic in this, but will it actually change things enough to overheat and kill the trans?

black.. my trans guy painted it..i am thinking it's fine !!!! i run two coolers on my rat

My trans guy painted mine black. I put a aluminim pan on it and it looks prettt sweet. Never noticed a heat difference between the old and the new, and i have a Autometer gauge

the 2 main shops we deal with through work (hvy equipment, big diesels and the such) all paint there trannys. They do it as an ID of sorts. Personally, I think a tranny should be silver, but many ppl paint them, even go with clear and wet sand and rubbing them out.

i've been painting trannys red for 40years it makes them shift smoother

If there a difference between painted or not it could not be that much. also I wonder where cdowns buys his paint because I want some

PAINT IT!

Is that an UltraBell bellhousing?

Have you had any issues with it leaking out of the front pump?

Same here. I painted my block gloss black so I went with silver with my trans and I think it looks good. Im a little stumped on what color to powdercoat the intake tho.

I haven't put one on yet but a friend I know that put one on and had an issue with it leaking a bit...

I am still gonna go the route of the ultra bell though...

cameeks · 01-22-2007, 08:11 PM

When I went through ASE for auto transmissions they were dead set against painting them.

I spent 2 days in class stripping my case that I got from

Extner Transmissions

and fount alot of problems with it. They left out filter screens in the valve body and the end play on the output and input shaft was way out of specs. Now honestly I dont have a trans temp gauge so I dont know if it changed the temp but down south here with an everyday driver I see it as going the safe route and doing anything to stay cool. If you clean the case up you can get them looking pretty good.

fastwillie 696969 · 01-22-2007, 08:15 PM

i would think silver be best since it will reflect heat rather than black which holds heat

LOL, is that the secret that? No longer need to shell out the money for a shift kit, just paint it!
Information like this could put B&M and TCI outta business

Personally, i like to just clean it up real nice before i put it back in. If I was creating an over the top, show vehicle, then maybe i would paint it, Otherwise i don't see the point.

My motto:
If it don't rust, it don't need no paint.

You already know my thoughts...

lilpup69chevy · 01-22-2007, 08:57 PM

paint it if you want its not gonna shift any better i'd just go with the silver or clean up the case look at tci trans in summit though they are painted black as well

**kwmech** · 01-22-2007, 09:57 PM

Been painting them for 30 years.

arkracing · 01-22-2007, 10:06 PM

I've also heard the "heat" thing. I talked to my tranny guy and he said for the amount of differance in heat it won't hurt anything to paint it.

I've also heard that Black actually pulls heat away and makes things cooler (motors, radiators, trannies) Not sure how true that is either

1971-tetanus-shot · 01-22-2007, 10:14 PM

I owned and still own VW aircooled cars( for over 12 years) and black paint or powdercoat (motors)has always cooled better then nonpainted surfaces, But even then it was only by about 20 degrees for powdercoat and 30 degrees for paint. But that is aircooled, I imagine the results would be less significant for fluid cooled

RACINJASON22 · 01-22-2007, 10:21 PM
