Quote from: HOLYTGPjust as a thought, not sure if it would work, but what if you took a tranny out of a GTP and put a better shift kit and converter in it?

You mean out of a 2nd gen(97+) GTP? If so, that's not very feasible and would be more of a headache than it's worth being that it is computer controlled..you can only go so far with them anyways(some hold power for a great deal of time, others crap out on stock GTP's driven a littler harder than normal).

Anything "GTP" won't work directly. The 3.4 GTP's were 4t60e's and the later ones were 4t65eHD. Both electronically shifted.

There is just too much heat in overdrive. Do you have the clutches at least doubled up in OD? I would add a much larger cooler if you haven't done so already. Later 4t60TGP were not supposed to go into overdrive which is why the top speed was 128mph, top of 3rd gear.

I havent actually went to a bigger cooler as of yet. We did double up the clutch material on the OD gear, but never added additional cooling. I don't know why I didn't think of that! Hmmm..... I wonder if I can get my FMIC, larger cooler, and still keep my A/C..... I'll have to try!

BRING THE TORCH!!!

Yeah, we were seeing repeated OD failures because of heat. Going with a much larger inline cooler seems to be helping. Either the factory cooler A: can't dissipate the additional heat B: Is clogged up with debris and not as efficient C: Doesn't get enough airflow. I would guess A and C because a couple of times I checked it with my hand and it was boiling hot. The extra large fm cooler isn't as hot but still gets plenty hot. I would guess you could mount the FMIC, then a trans cooler and then the condenser. Or put the trans cooler right out front of the FMIC. If you can find a long one you could make it so it covered the mouth of the front valance. I've seen some trucks with long trans coolers so it should be available.

I've been looking through some of the aftermarket kits available, and I'm thinking of something kind of odd, but it just might work... How about replaing the stock cooler, and ALSO adding a good sized FM. Daisy chain them together, and then build some sort of scoop to pull the air through them, possibly out of carbon fiber? I'll have some left over after buiding my sub enclosure/amp shelf. I was also going to use some to strenghten the valance. It might help feed my FMIC as well. The condenser can stay behind the FMIC where it's at.

Also, I wonder if changing trans fluid to B&M Trickshift might help a bit. As of right now, we've been running stock GM.

The other thing i was thinking... My turbo is probably a big contributor to the heat, since it's right above the trans. Maybe if I wrap the turbo, to shield the trans from the heat, and maybe place a heat shield on the top of the trans, that will help some more...

Can you tell I'm tired of trans swaps?

DEFINETLY switch to Type F (Ford) tranny fluid.  Every performance builder I know uses Type F.  The race tranny I bought (TH350) came w/ destructions to use Type F fluid.  The only difference is Type F is designed to run hotter.  B&M is designed to run even hotter but it's like $7 a quart, and it doesn't provide that much more protection than Type F.  I use type F in all my cars just for added heat protection.

Wow, Ford did something right?!?  J/K. I actually sell B&M, so I have a bunch of it already. But the type F sounds like a good idea as well.

Plus the B&M is a cool ass blue color.   8)  :lol:

Hmm...I was just thinking....Rebuilt stock trans every other month till you get tired...or shell out $3K and be done with it and spend money on mods...Just my two cents.

And why do you see it as being more than the cars value...LOL...
I think its a good investment.


I've seen peole put $3K sterio systems on cars than ain't even worth a crap..  :lol:  Now thats a waste of money..... to me.

hi, i was wondering if you use a top gun 160 and a manual boost controller, won't you have problems with fuel and timing stuff because your chip regulates for a certain amount of boost...
im prob wrong, so could some one tell me why the boost controller would help if you don't really raise the boost psi
thanks,
mike

why will using a manual boost controller give you more hp if your not really raising the peek psi... and if your using one with the top gun chips won't you get problems with fuel control and time and stuff... some explain to me please
thanks mike

sorry didn't think it sent...my bad :oops:  :oops:

Yea that was a lot of posting, I think someone is excited about their upcoming TGP, like all of us when the first drive happened  :lol:   Over the years many other turbo cars out there could use a manual boost controller, long as there was not a fuel cut when you went much over stock boost, though some guys came up with fuel cut defenders to bypass this problem, but really and most important is if the chip is tuned to run more boost and be safe :!:   Back to the TGP, fuel cut happens pretty soon (9.5 psi or so) unless you have bypassed the fuel cut, not much gain here with stock chip, but if you take out the fuel cut, you can raise the boost to around 12 psi BUT need to work the rest of the chip to run safe there!!  Tuned properly this adds a lot to the powerband NOT just the peak hp gain at one rpm quote.  I setup my chips to ramp boost up at less than 3,500 rpms at a rate to assist in maintaining traction and good 60 foot times, then past 3,500 rpms, boost is up to max safe level where it stays till you run out of road or take your foot off.  Why would anyone need more boost at less than 3,500 rpms is beyond me since once you have launched and spun the shit out of your tires, your engine will never see less than 3,500 rpms after that and your boost is locked at 11-12 psi, nothing else to benefit from a manual. THE only thing with manual is you just took out a key safety feature in the chip that protects your engine!!!

As far a level 10, I haven't heard about them lately. But arron Lephardt (??) had quite a bit of problems with their trans upgrade in his SC GTP Conversion GP. I also noticed they said PTS which is a company in california that does a lot of GN trannies. Maybe they are just sending them out/using their parts?

Chris

I wanted to bring this post back from the dead to add a little information(just in case anyone uses the search function and wanted to know about this).  The "PTS" that Level 10 lists on there is not the same Performance Transmissions company in California.  I contacted the company in California and they said they do not offer any parts or build any FWD transaxles.

Also, steer clear of Level 10....
