The two words "cheap" (or inexpensive) and "good" don't work well together for our needs.

Least expensive way to go is to build your own valve body using a kit like the TFT-Diesel kit from Transgo. Billet single disk torque converters start at about $500 and go up from there. WIT (Whatever It Takes) offers a billet single disk converter for under $300, but it is of unknown quality. It is built by a major builder and they've not had problems with returns (I live in Louisville, the home base of WIT and have talked to the builders). I'll probably run one of theirs in my own truck. FYI, I'm just looking for a reliable tow rig, not a big hp smoker, so my needs may vary from some of the other users on this board.

how much is "some" power and what are you calling a "budget"?

Before I post, I want to say that this is my opinion and that others will probably have something different to share...

That being said, I see a break between 300-350 and 350+ in horsepower as far as the needs in a transmission build. At 350, you can get by with a single plate billet torque converter and a valve body, easily done for your $1000 budget. Get with any of the great vendors on this board and ask them for a quote. At 400 and up, you are looking at a triple disk billet converter (over $1000 itself), a valve body ($250), billet input shaft ($750), high end clutches, steels, bands, etc., (another $300) and perhaps a billet output also ($500).

Adding power = adding torque and it is the high torque that starts taking stuff apart. At 300-350, you are probably in the 700-750 pounds/feet range for torque. Go to 400 and you are probably nearing 1000 pounds/feet -- above the designed parameters for the transmission, hence the additional parts to handle the load.

You'll probably also need additional cooling for either build.

So, up front, so as to not waste a bunch of money with a build that just has to be done over, you might want to consider just how much power you want to make and plan accordingly. Our trucks readily take to power -- and it is relatively easy to build for power, but if you want to play, you have to pay. There really are no shortcuts in this process as any number of people who have gone before you will attest.

The trans on a 95 is going to require some internal work to handle a shift kit and that much power. You should probably rebuild.

the inside of the trans is ok for that power range, around here i can get a single disk dacco convertor for $350 or $400 and a kick *** vb from dtt or ats for $420, the bad thing with the 47rh is that the line seals for lock up are weak so you cant run alot of lock line pressure on the stock seals, all the good internals parts are cheap compared to the vb and tc, you could get all the good clutches and seals and get the upgrades to put more clutches and steals in each pack for under $200, its the labor that will kill you

if your going to stay in that power range a single disk and vb will do you just fine imo as long as the rest of the tranny is still good and not on its way out
