Need a high performance 4T60 TGP Transmission

[TurboGTU]

Why away from level 10? Has it gone bad like yesterdays tuna sanwitch?

I've added type F to my 3t40..and I must say that thing holds like no ones buissness. Then again..I have red clutches.

I'd try some type F on the TGP..but it needs the rebuild.

Type F is a high friction fluid, and also wistands high heat. Other fluids have a "slip" affect. Think Dextron III,  V. Some trannies don't like type F though..so use caution.

B&Ms trick shift is Type F.

Pretty much. :wink:  I've heard of quite a few people having issues with products from them(parts not holding up to the level they claim they will).


Oh yeah, I made a post in General also about our transaxles(a source for a stock rebuild anyways). I should have some information on kits, upgrade parts, etc. for us that are performance oriented as well(I'll share any/all information on come across). 8)

Any news on tranny upgrades???

No, but we would like to know which line flows away from the tranny. Anyone that gets there tranny flushed , please note the direction of flow.

Then we could place a temp. sensor on the hottest part of the tranny.

Waiting to hear back from the one company I've contacted so far, we've exchanged a few emails back and forth, but now it's been a few days since I've received a reply. I'm fixing to call them and also a few other places.

TTT?

TTT?

I still need to get back in touch with a few places to try to price out some packages and whatnot. One company I contacted did not even bother responding back after I told them I was only gauging interest in pricing at this point. :oops:


I'll list a few places that I've found that should be able to build whatever you need within reason.


Certified Automatic Trans Svc
(616) 459-0935
842 Fulton St W
Grand Rapids, MI 49504

The transmission/transaxle chain "Certified"(an internet search will bring up a lot of locations their business chains are located at) also should be able to build performance versions of our transaxles, they offer stock rebuilds now available for order. They do not appear to be the same company I listed above(the company above does performance work for ZZPerformance, which most of us know as one of the leaders or the leader in the later model 3800 FWD community.)


http://www.dynotechperformance.com/

Dynotech is another very reputable company that has built 4T60-E's, etc. for a lot of faster FWD cars(they only list the late model Grand Prix's on the site, but contact them and they will work with you.)

Well look at your radiator...there is a line coming in and a line going out to your fender mount tranny cooler. 99% of any tranny cooler flow will go in the radiator first and then out to an external cooler and back to the tranny.  8)

Actually Kenny I was told that it's the other way around (not in all cases, but it makes sense, kinda) because if the aux cooler is TOO efficient, and the fluid temps drop too much, it could be bad.  So they send it to the aux cooler, then to the rad to keep a stable oil temp going into the tranny.  I'm not saying this is how it is, but was told that.

BTW, I've got someone putting a kit together for me.  He's a custom converter builder for a racing company in Kentucky.  He BUILDS them, and also does racing tranny builds.  He's my sisters friend, he knows his shit too.  I've got a custom 'verter down there right now, but the tranny is shot... So no need to pick it up.   :evil:   So, he's making calls and getting some shit put together for me.  And I have a local mechanic that knows these trannies inside and out, and does rebuilds for $150 labor.   :shock:  I was told that the kit and all the extra shit (he sat there and explained to me what happens w/ the 4T60 poo's itself, and he said alot of times it's the same problem. I didn't listen, he talked for a long time.)  I need to keep it from happening again, would cost about $300-$500, w/ doubling up o/d.  Then my $150 labor, and he personally guarentees me this tranny to ~450 HP and Tq.  The main limiting factor is the 'verter because it was built for another guy w/ just a stock 3.1 that wanted it a little more fun to drive.  We'll see.

Jeff,

   Please keep us informed on the Tranny upgrade...there are many of us that would buy these kits once someone verifies them.  I wont be driving my TGP for a while but am very interested.

Thanks,
Thomas
