Exclamation Level 10 Transmission Superior Durability?

Question...I've been reading for a loonngg time about the virtues of the Level 10 transmission. How long have you members had them, I know you drive them hard, but how do you know that they are gonna hold up any better than the stock transmission? I've seen 4EAT trannies last well over 100k, are you guys at that mark? I'm curious because if you say it's bulletproof, I'd recommend the updated valve body etc, but *only* if you can show documented proof that it does outlast/outperform the original trans. (Even non-SVXers could use the updates on their Legacys and Imprezas after all.)

Well KevinObrien was the first club member to get a rebuild done 13 months ago. I think he's driven over 20,000 miles since then. Mine was rebuilt in March and I've driven just a few thousand miles. There have been many more that have gotten rebuilds/valve body mods from Level 10.

Shotsky had his valve body modified when he swapped trannies, and I believe he has driven 20,000-30,000 miles since then.

The argument that 4EAT's with Level 10 modified valve bodies outlast standard, "non-modified" 4EAT's is that they improve circulation which keeps ATF temperatures substantially lower.

After testing, ATF flow was found to have DOUBLED after the modification. Then with some "real world" hill climb testing, before and after results showed a 60 degree fahrenheit decrease in temperatures(from 213 to 154)!

If you check with some of the transmission websites, they have charts showing that ATF operating temperature has a DIRECT effect on transmission life. 200+ degree transmission temps had tranny life below 20,000-10,000 miles.
150 degree ATF temps had up to a 200,000 mile tranny life!!

We don't have any ACTUAL reports about how long Level 10 4EAT's really last, but we don't have any reports of failures either.

Of course it depends WHEN you get the valve body modified. If you get it done RIGHT when you get a brand new rebuilt tranny, it'll last much longer than if you get it installed when the tranny was already on it's last legs.

The Level 10 valve body can't give back life to your tranny, but it can SUBSTANTIALLY stretch out whatever life it has left!!

"Of course it depends WHEN you get the valve body modified. If you get it done RIGHT when you get a brand new rebuilt tranny, it'll last much longer than if you get it installed when the tranny was already on it's last legs."

I can attest to this in my Impreza OBS and this was probably a couple weeks after I got my valve body done. My tranny was on it's last legs and I really believe the valve body job helped preserve what little life it had left. Thanks BlondeMan for the recommendation and the short 'follow-the-leader' trip through the mountains while I was coming back home. Your car is really fast once it's moving. You would've left me for the vultures for real. Hehe!
