One of my friend is driving a 1994 LT1 trans am. When you are driving over 200 km/h and then you want to drive a little bit faster, than the automatic transmission is going very fast one gear down and the engine scream up. For example, when you are driving a LS1 automatic, then it will not happened.

Is there anything, what he can do, that this will not happened? A module, power programmer or somethin else?


I hope, you understand, what i mean. (Bad english)

Programming

I don't think programming will do it. There is a valve for the 3-4 shift that has to be either modified or replaced. I could be wrong on this. My 95 Camaro Z28 was the same way. Under wide open throttle it would not shift from Drive to Overdrive. I replaced the tranny with an aftermarket high performance tranny and it would shift to overdrive under full throttle.

i know, that i can buy a valve for the TH700 transmission. But i can´t find one for the 4L60E.
I don´t know if the hypertech programmer will help...

Jens, what's up with the "Sold" on your sig picture? Had it on there last night, gone now again ... don't tell me you're selling the V8-converted 'vert after going through all the trouble?? (guess it's all dependant on the price somebody's willing to pay )

i´ve sold my camaro last week. The money was ok for the convertible.
I sold my camaro, because i want to buy a house.

Sorry to hear, and congrats for deciding on getting a house ... hope you find something decent and affordable!!!

And just pick up a new 'maro in '08 with the LS2/LS6/LSwhatever

and just noticed it's still there, just the browser chached the old version of the pic ...

hey jens good luck with the house and I agree that a house is better then a car. I know in the 700r4 you could get a vette servo or 3-4 valve I don't really remember. I don't know about the 4l60 I really don't know how much is computer controlled on it.

I´m thinking of buying this LT1 trans am. It is a 1994 with 69000mls. US-Modell in black with darkgrey leather and t-tops. It has german papers, etc.
It is better, to keep the money for the house, i found a very nice house, lets see, if i can buy it. The decision of the house will be on march 8th.

Thanks for your wishes.
When somebody knows more about a valve or something else, please let me know.

Jens ,
Part of the problem can be solved with the Vette Servo (see URL: http://www.700r4l60e.com/store/catalog/ ... p-162.html) for an example. I have 3 F-bodies & two use the 4L60 trans & high speed driving with a weak 4th hold will start to burn the clutch pack.

Superior makes a kit (P/N A74902H ) that is advertised as: "700R4 / 4L60 / 4L60E, 4th apply Super Servo by Superior
Superior # K034, comes with 4th apply piston, cover and seals for better holding capacity in 4th gear. Lip seal design ".

I hope this helps a bit!

This helps alot. Thank you for the info.

Remember that our cars will produce a lot of heat in the trans at high speeds (US Freeways or on the Autobahn). I have never noticed a trans problem at 200 kph (125 mph) but it is very rare that I can keep these speeds up without having full air & ground support from the CHP (California Highway Patrol) or Autobahn Polizei as I remember them in Germany. There was one event where I was able to do 145 mph ( 233 kph) for about 4 minutes when I noticed the dropping out of OD issue. About 5 months later my Z28 had burned 4th gear clutches. You can guess what parts were included in the updated rebuild. Now, I use 28,000 lb trans coolers in all of my cars & thats running 160 degree F thermostats. Watch your readend oil also, I use Amsoil 100% synthetic to help the rear stay cool. The 3.5 hours of high speed desert driving between the California coast & Las Vegas during the summer can be a real trans or rearend killer!! My next trans update will be with a modified 6L80E & I can't wait to get started, 400+ hp & 6-speeds!!. I will ship one of my cars to Germany during a business trip to "test" that trans out. It should support 180+ mph (290 kph) Autobahn runs with very little engine changes.

Good luck!
