Precision 4T40E rebuild kit
Wednesday, February 27, 2013 3:05 PM
Anyone have any experience using a 4T40E rebuild kit from a company called Precision? I couldn't find anything while searching. I talked to someone there, and he said the quality of the internal parts exceeds factory components. They do not claim a certain hp/tq rating though. Anyway, I'm looking into this because a complete rebuild kit (except solenoids) is $260 shipped. After the issues I've had for my build, I'm only going to run 12psi boost (turbo). I had planned on upwards of 20psi for a while, but that will end up costing more and more money. Supposedly, these trannys stock can handle 300-350 hp, so at 12 psi and the fact I'm in high altitude I know I'm not going to hit 300 whp. So, any reviews on a Precision rebuild kit?

most aftermarket companies for ANY parts will claim their quality meets or exceeds factory requirements.

id check into exactly what they mean. my guess is its just a standard stock rebuild kit.



It's nice to be injected but I love being blown.

ALL GASKETS / SEALS / OE CLUTCHES / ASSEMBLY LUBE / ASSEMBLY TECH INFO ARE INCLUDED.

That's from the website. I guess I should email or call back for specifics.
