Re: (red L98)
Having had 6 tranniees replaced in my 1990 I speak from experience, when I say, that the tranny is good under light loading for overdrive gas mileage type people. Those of us who flloor the Torque monster at redlights, do damage in several ways. The stock TC will eventually shred vane parts as they are bent under the immense pressure. These little bits of metal clog the small openings that the fluid has to travel. The heat is also a major contributor in the fluid. The 3/4 clutch pack will always go first, did every time in mine, except for the time the planetary sun gear left the case. Probably also heat stress realted. If you insist on driving the car hard, go for hardened parts and heavy duty clutch plates, and improved bigger fluid pump, an extra tranny oil cooler. Look at http://www.Levelten.com website and/or call him. There is another company in Louisianna called trex or something that sells hard parts too. Don't put another stock tranny or TC in the car without expecting it to fail almost immediately. :smash:

Re: Another Tranny Gone!!! (mn_vette)
So I guess this is what I should do:
1.) New Rear end. 3.07? 3.45?
2.) New torque converter. 2500 stall is what I want
3.) Tranny temp gauge. More pillar pod work, yay!
4.) Oh yeah, rebuild tranny.
Anything else that I'm missing?? The comments were very helpful please keep them comming!! :yesnod:

Re: Another Tranny Gone!!! (mn_vette)
You just need a better tranny built. This is a picture of my buddies 950rwhp 850 f/lbs 300zx. He is running a 700 r4 in his and its at the track every weekend. You ready for the funny part???? 7000k-rpm neuteral drops. That is right revs it to 7k and drops her into gear. with a 150 shot of NOS behind it..Race slicks. runs 9.80 @145 ish

You might want to reconsider your converter choice. I have a 2600 stall behind my stock Crossfire, and I think it could benefit from more. Good luck, and...

I do not get the neutral drop thing. Automatics are known to be better for boosted cars.
Revving a turbo car in neutral does little for building boost. You need load to build boost. Tell your friend to stall it a bit, build some boost and He'll be better off.
The 950 hp thing and his mph don't add up to me either Scorp. I've told Rich that on AIM a time or two. :confused:

Re: Another Tranny Gone!!! (scorp508)
How does 950rwhp and 145mph match up? :confused: High boost for dyno queen # and then then lower the boost for the track?
For example a SUpra Turbo putting down 700HP at the wheels, 'only' runs high 10's..

Yup, turbo cars can dyno like nobody's business, but at the track they don't run anywhere the HP #'s should.

That was the problem on the first two tranny's when the torque converter wasn't locking up, it would take out 3rd and OD. Now there's a lockup set to go whenever it's in 3rd.
You have 5 transmissions that PROVE this point.
With the TCC locked you have absolutely NO "soft coupling" between the engine and the transmission when it shifts into fourth.
Nothing but WHAM,BAM THANK YOU MAMN.
When the TCC engages in third it's the same situation. KA-BAM.
LISTEN:
GO BACK TO THE FACTORY DESIGNED TCC CONTROL AND LOCKUP METHODOLOGY. You can modify TCC lockup with ECM programming but it WON'T be a hard wired kludge like you've got now.
Unless of course you can keep getting new transmissions under warranty and you LIKE changing them out.

Re: (mn_vette)
Well, in either case I called my mechanic and he said that he wouldn't rebuild it unless I changed the gears. So I guess I'm going to rebuild it myself or I'm off searching for a new rear end.......
anybody know of someone selling a dana 44??? :confused:

Personally, I find it rather interesting that your "weak" D36 has outlasted all those failed trannys with the ponies and torque that 396 is putting out, in spite of the 2.59 gears.
But yes, I would also definitely find another tranny mech.....or as you say, do it yourself.......and add a 2400-2800 stall conv while you're at it.

Re: Another Tranny Gone!!! (MrNuke)
I know I'm getting totally off the subject, but someone posted a video of a 10.40ish supra with 700RWHP like Mr. Nuke mentioned and although I thought the car was quick I told the gentleman that I was not impressed and I got hell for it on a previous post. I work around alot of imports and they make a ton of Dyno power but it seems that they need alot more power to ET when compared to let's say domestic powerd cars with the same HP. I believe Turbo cars make up most of their time halfway down the track because most are not boosted properly at the starting line and neutral dropping is not gonna help anything. The guy with the Z should try a timing retard to get the boost up at the line. It works pretty good!

that 700 rwhp supra proabbly makes 700 rwhp for 100 rpm or so.
They have really "peaky" h.p. curves where it looks like the side of a mountain versus a flat horsepower dyno sheet.
