Just a tad ;) .

I'm building a 60e/65-hd hybrid for the Beretta. I was able to assym it using the 60e driven support on the 65 guts. Something is off on that 4t60 I have . 6mm seems a bit off. Wasn't the 3 mm I quoted. 

Up to 1996 w-body driver side 4t60e same as TGP driver side. PAss side 4t60e axle shorter need that axle. 4t65 need both cv axles.

For the 3.29 regular 65e yes but need the diff ring gear housing  but cut down shorter like the 4t60. I wouldn't bother with it as the 4t60 3.33 is plenty good. The 65-HD diff doesnt fit. Its wider and taller while using a roller bearing on theouter passenger side . If your set on the HD diff you need to use a 4t60e  with something to shift it or use a trans controller setup with a whole 65e. The 60e is easier as it uses a vacume modulator and only need to activate the shift solenoids. You need the  91-96 w-body 4t60e CV axles as spine count is different . I need to verify first. 65 is suppose to be the same as the 4t60 spine count but need the pass side CV axle anyway from a w-body 65e

Digging this out of the grave  :icon_rolleyes: . Mostly do to a new aftermarket part being made.
http://www.sonnax.com/system/announcement/84965-01K.pdf . 3rd clutch piston with 50% more clamping force. On the 4t60 this will allow more clutch space too. Was meant for the bonded small piston setup on the E transmissions. I haven't got a price for it. One source I found said expect 150 range.

Also those looking into the 4t60/65 h6brid need to use the sprocket support from the 65e but turned down on the driven sprocket end about 3 mm on a lathe. Measure first. The 4th piston needs some grinding down on the apply surface as of sits too high in the 65 sprocket support.  I haven't found a solution for the 440t4 that have a Lupe hole on the side to use the 65e guts. I'd say update to a whole 4t60e/65 hybrid or go all out 4t65e ,HD.  The 60e can use the 65hd differential.  O

It was a fat pig starter.  These new starters are a god send. The one on my 03 grand am is smaller than the first gear reduced starters from the 3*00.

Nice find. Wonder if its cat back or whole omitting cat.

NICE  :icon_cool:

I've been away from the TGP for months. So much so that the garage sprung a leak and ruined my 4t80 the non-viscous converter is safe though. The original tgp engine that I loaned to the Beretta is all rusted too. Had pulled the heads and walked away for over a year. Needless to say, I'm shopping for another 4t80, I'm also planning a 3900 with LS1 forged pistons and 6in rods using either the TGP crank and have it Cryo-treated or use the 3900 crank and have that cryod but use an external trigger. I have two VGT turbos ready for a twin setup that flow enough for my goals. They each powered a 2007+ 5.2l isuzu NPR.
I'm planning this out as my new daily grind vehicle as the grand am I'm driving is neering 230K miles on the original drivetrain minus heads. I know it will still kick up to or past 300K miles but give me an excuse to spend my money on the TGP rather than a new/used boring car.

It's a must now. Stock fuel lines AT the engine side are toast. 

Twisties !!!

Wow ten years already? Time flies.  I'm glad I was around for both sites and all the people that came and went along the years. Seen some bad as TGP along the years and hope to see more.

Got the cage, balls , race from a 96 4x4 s10 blazer.  They fit perfect in the TGP joint and 4t80 shaft.  The TGP and s10 both have .750 diameter balls. Other w-cars I saw had smaller size but were the 3.1, 3100 type. Now on with the build.

From Chris A. what he did.

Sounds like a good plan  :icon_cool:

Think I just hit jackpot. I will replace the inner race from the outbard. THe race from the TGP has 32 spine hole. The olds 4t80 shaft has 34 spines.  Looking at 79-84 toronado, riviera, eldorado seville, 90-99 lumina, 90-99 apv lunmina, 82-96 chevy truck, 91-98 Dakota saginaw desighn, 82-96 s10/ blazer and GMC sonoma, bravada, Jimmy.   This will retain the TGP outboard joint , cage and balls.

My thought of getting bigger cage and balls won't work since the race and joint have to have the groves for those balls and cage has to fight tight in the joint.

Well I'll see if I can get some time during lunch and do a quick look see.

I'm guessing on the luminas it's the 3800 variety. SO maybe 98-99.

Edit due to having wrong cars. These are right.
