auto tranny up grade questions

If I upgraded the torque converter and put on upgrade valve body will the rest of the tranny hold up if so how much can I go up in power with just doing these mods I would like to do the whole thing but 3500.00 wow.

My guess is you would just add more stress to the rest of the components causing them to fail prematurely. <br> Personnaly I will not start upping my own power till I have the Tranny to handle it. Which hopefully will not be too long from now!

Re:auto tranny up grade questions

All depends on how you drive. My auto lasted for 320,000Km. The trannies are not really bad, but remember to keep the revs up before going into OD, and limit the number of WOT starts from a stop.<br>Hope you get the right stuff!

Re:auto tranny up grade questions

think about throttle/line pressures versus your power curve/shift points...and many other factors. like i've said before, i know someone who has put 82 or 85,000 miles on his truck with just a valve body and torque converter. he's had BD8's in his truck for at least 5 months that i know of, NOS, twins, FMS, etc...making 640hp at the last dyno day. he says that he raced almost every weekend...never broke a shaft or anything (yeah, he CAN drive his truck like most us can't-taught me a lot when it comes to that stuff). Now the tranny is broken.<br><br>i'm not saying it's the best thing to do, because it's bound to break sometime or another, but those two alone can hold some good power and be reliable.<br><br>Tom

Re:auto tranny up grade questions

Just the valve body and torque converter would be cheaper.
But, Heck, why not go all out and get the whole transmission.

3499.00 but figure in shipping and install too.
Do I hear 4,000?

How 'bout billet input and output shafts too?

Re:auto tranny up grade questions

Seems like just getting a converter and valve body would just put more pressure on the rest of the tranny<br>

Re:auto tranny up grade questions

Top if you get the upgrades along with them you will be getting the same as you would with the whole trans.

Re:auto tranny up grade questions

The TC and VB is the trans other than a few clutches, gears, shafts, seals and gaskets that can be upgraded. And the trans case.

boughtadodge:<br><br>The other members have already given you some<br>good advice!<br><br>Don't make the same mistake I did. At about 98,000<br>miles my &quot;stock&quot; transmission was beginning to show<br>wear. I began to experience the familiar 4th gear (O.D.) <br>&quot;shudder&quot; when I was towing my racing trailer in the<br>mountains. Thinking I could &quot;get by&quot; with just a new<br>TC and valve body after that many miles turned out<br>to be a mistake! About 3,000 miles after I had the<br>new TC and valve body installed, I began experiencing<br>a problem where the tranny wouldn't shift into third<br>gear right. Anyway, I ended up having to back into<br>the tranny to have new seals, clutch packs etc.<br>installed. <br><br>I would recommend saving up the money until you<br>have enough to completely go through your entire<br>transmission. This is especially true if your truck<br>has alot of miles on it.<br><br>Good luck!<br><br>---------<br>John_P
