In about two weeks I'm either going to by a tranny mod. What you guys think LVL 10 TQ converter or GTM VB upgrade? Maybe some gusy with either can chime in. Thanx guys

 

Getting my IPL back from GTM this weekend (fingers crossed) with a VB upgrade.
I'll let you know how it drives.
Full disclosure - it'll have twin turbos pushing on the tranny

 

I love my transgo valve body upgrade. Its the best thing i have done to my car!

 

I'd do both to be honest, it's not everyday that you have your transmission dropped

 

Thanx Wattles, I have a SC kit so very similar, Your just making WAY more TQ than me, But would love to know how is stifts ,

To G37SAM, I agree but thats like $2k in parts, I have just shy off that saved for this, Took me a year to save for it :/. With two houses,. it's hard save $$ for the car. LOL

 

Does anyone know what the difference is between the GTM upgrade ans the transgo.

 

Anmvq, check out this guy

 

WOW thats pretty much CRAZY, Only thing I dont like is the exhaust, LOL . But that is a SERIUOS X coupe.

 

I thought that GTM uses the Transgo kit for their valve body upgrades.

 

Thats my buddys X. I cant wait till it gets back here. He just decided to do the 4.2 about 2 weeks ago!!!

 

Nice! The video says it's only a baseline dyno, so I assume your buddy's G is the test fit car for the twin SC? Hopefully we'll be able to see the final production soon!

 

WOW lucky guy , So now there two of X coups FI. all tho he's is WAY FASTER,, LOL Can we say ,, He also was not worried about the T case at all? I know I still have concerns with mine at 400 WHP at like 650ish, I think it would be a concern no?

 

Maybe I am mistaken, but the VB upgrade does not require a tranny drop.
It is my understanding that all work is done from under the trans. Where the cover on the bottom is removed.

Still crossing my fingers to get it back Saturday!

 

Funny cause now I do not think I'm doing anything... I talk to Rich at UPREV for about 20 mins ago, about this and he told me they experience with these upgrades and the uprev tune,( SC G37-Stillen kit, and a SC truck) he told me to stay away from these mods. Just weird cause he actualy told my the trans is very good and with a upraded TQ and or VB the tune has a hard time controling shifts and the tranny kinda does what it wants, As long as my TQ tables have been changed he said I was fine. ?

 

What are "TQ tables?"

You do not need to drop the transmission to do the valve body upgrade. You do have to drop the transmission to swap out torque convertors.

Some transgo shift kits come with a few extra parts that go deeper into the transmission but those are normally left in the box unless the transmission is already out.

I would stay away from a torque convertor unless you are making serious changes to the engine. No reason at all to change it.

Valve bodies are the heart, soul, and brains of the transmission. Newer transmissions have a lot more computer controls but it still comes down to the mechanics. This particular transmission (RE5RO5A I believe) is more mechanical than computer driven. Tuning will only get you so far.

Some outfits that really know their stuff will do a lot of custom work to valve bodies. It's not uncommon for them to use a Transgo kit to start things out. The right springs and parts are in the kits and it gives them a place to start. I do not know any details of these custom valve bodies for these RE5RO5A. I understand that the information has to be protected, but no one talks about this kind of stuff at all in the import world.

The best transmission mod is a well put together valve body coupled with a good tune.
