How rough is a 3200 on my LT1

So i have a Vig 3200 stall, im still a bit new to this whole deal. I have a "CPT Race" transmission. Since ive had this, ive noticed that my engine has to obviously work a bit harder to get the car moving. How bad is this on the engine and driveline? I want my car to be a street machine. Daily drivable if needed. So should i use my free rebuild to get a lower stall rating? Or is this not as bad as it seems for the car? If it makes any difference, the car is getting the LE1 package here shortly aswel.

What rear gear do you have? The lower the gear, the more it feels like the motor is working harder. 3.73s with that trans, converter, and definately a LE package would be the way to go.

The car that its on now has 3.23 gears. The car that its going onto has 2.73 gears but i do plan to have 3.73 installed immediatly.. So with 3.73s how much of a difference would i notice over the 3.23s? Its pretty bad as it is right now.. Thanks man.

I just put in an edge 3400, and it is great. It seems like the motor is working harder, but it shouldn't affect anything.

What does BTDT mean Zrated?

I find it hard to believe that a stall converter doesn't reduce engine life or anything. I mean its gotta be up at 3200 rpms to get the car moving really, and to maintain a highway speed of 60 mph i gotta be at 3200 rpm the whole time. That cant be good on gas, the trans, or the engine...

Somethings not right then..the converter should be locked when cruising at 60 and it shouldn't take near 3200 just to get the car moving.

Been there, done that. 3.73s are a good choice for a stalled auto, but somethings not right with your car. I have a Yank 3600 now and it does not take much gas pedal at all to get the car moving. I have an aftermarket tach (Comp) and at about 62mph I'm turning 2200 rpm. The stock tach reads 2350. Sounds like your converter is not locking up and maybe some kind of more serious issue is happening. Better have it checked out.

Oh great... Lovely. Ok so in order to maintain speeds at 60 mph with my CPT trans on a car with 3.23 gears i need to be over the stall point or whatever... And thats not normal? Okay ima break this down about how and why i bought this...

First off, i dont know how these work or why they help your acceleration times.. I bought a "Race" rebuild on my trans for my 97 when the factory build gave out. To accompany it i purchased

http://www.thunderracing.com/catalog...3&sid=297#P878

Its the first TC on the list "19VIGILANTE" It was recommended by a friend and he said a 3200 stall would be good. When i got the transmission installed, i didnt have a trans cooler in it. Me being the d/a that i am i didnt think nothing of it. So i took the car for a test drive.. It was fine. So the next day i took it home. After my trans overheated and the fluid turned to a smoke cloud behind my car i was about 3/4 of the way. The car didnt want to shift. It was acting funny. So i was like wtf. I got some more ATF and poured it in after i called a couple mechanics including frank. They told me to put more ATF in it and run it through every gear. So i did that. After hitting 100 mph i saw a smoke cloud behind me, let off and immediately pulled over. Called frank and he asked if i had a trans cooler. I said no. Needless to say a trans cooler went out immediately. Now since i dont have much experience on these things, i dismissed any major damage after letting a GM mechanic test drive the car. He said it was okay and there was nothing wrong. Sooooooooo with that being said.. What have i broke?

You definitely need a good trans cooler, my car shifts great with the 3400 stall and converter...ask frank what he thinks about it. He might have an idea.

You didn't do anything wrong, that this problem happened on the way home from the shop. A trans cooler would be nice, but that's not what caused your problem, in that short amount of time. Sounds like maybe an improper install. Who knows? Call Frank and see what he thinks. Call the shop that did the work and tell them what happened to your expensive trans and converter and that your not to pleased.
PS, I think Franks transmissions are well worth the money and will be getting one sooner than later. No disrespect meant about the expensive part, there not.

I agree franks work is great. I was very pleased with it.. DHL on the other hand, can FOAD....
The problem with the shop that installed this trans, is that it was done at my father in laws lol.. He pretty much did it all, i helped here and there, but mostly watched and learned.... Im glad to hear that my stupidity hasn't necessarily destroyed this thing.. Being an E3 in the Army means you don't make a lot.. So this would pretty much crush all performance plans for my '94 since im wanting to get this trans and TC swapped into it. Ill try to get ahold of frank when i get the time.. Hes a tough guy to get ahold of and when you don't have a phone near by all the time, it makes matters even harder. Thanks again for your input man. You have been pretty informative and helpful whenever i have a question.
