Having my 47rh rebuilt/ how far to rebuild it?

I talked to my tranny shop and was told the following about the rebuild.

A stock rebuild is 1395.00 without a converter. A stock
converter is $530.00 A billet converter is $995.00. you can upgrade the
planetary to a 5 pinion steel front for 449.19. A 6 pinion rear for 321.56.
to add extra clutch to the direct clutch is 74.95. To add a clutch to
the forward clutch is 124.95. A shift kit is 150.01. to change the o.d.
direct clutch to 10 clutches is 124.95. 6 od clutch would be 49.95.
give me a call if you have any questions. Thank you Mike


Knowing that I told him about my desire for dtt torque convertor. Can anybody shed some light into this rebuild so I can understand it?

Goal 350 hp and 700 lbs torque give or take a few...

Thanks,
Danno

I've asked question before with very little input. I kind of lost interest in their forum.

PM sent on some different prices for those parts. If he says anything about labor then he's yankin your chain because all those parts come out in the rebuild. Also, if he goes with a Borg-Warner master rebuild with steel separator plates all those extra clutches are included in the rebuild. That would be another thing I would ask about it what kind of friction discs he's using; BW, Raybestos, Alto, OEM (<- that list is in order of quality/power handling's)

As far as explanation of things:

- Front gear: Stock is usually aluminum four or five pinion planetary. The intermediate shaft is splined into the carrier so you can see why steel is important since those splines are easily wiped out in the aluminum one.

- Rear gear: Usually a four pinion the rear gear is first gear and takes a lot of abuse getting things off the line. The shaft is not splined into the carrier, so in this case aluminum would work fine. The idea of six pinion gears is to more evenly distribute the load on the carrier and make more gear to gear contact.

- Extra clutches: Just a part of the rebuild kit that uses thinner separator plates to allow an extra friction plate to be added. This is like putting a bigger clutch in a manual; it puts more friction surface in the clutch pack allowing more power to be held without slipping. Also, if he makes that seem like a lot of work with changing out clutch drums and the like then you can call his bluff and tell him that the BW kit comes with extra clutches in the kit that fit WITHOUT modification.

- Shift kit: Usually increases line pressures and shift points. Also most kits increase flow to TC's fluid coupling while not in lock-up which brings down temps. The increased line pressure is probably the biggest benefit though since that helps your clutch packs and the lock-up clutch(es) in your TC hold more power (kinda like putting stronger springs a pressure plate on a manual).

Hope that helps you out as far as understanding, and I hope my PM sheds some light on true costs of trans parts.

Thank you, I wanted him to know why we change these parts and what all is actually done while we're in there. As an agricultural mechanic (my main job) I don't like seeing people get taken advantage of because they are uninformed about what is available as far as parts and the true processes of the rebuild or repair.

That price is a little steep.

CKT has coverd a lot of the information that I was going to post but I decided I'd look at his post first because I figured he would of covered it.

I would ask him if he is going to tear down the valvebody (take valves out) and clean it propperly.
The steel plantary is a good upgrade.
Also you gotta watch overstacking clutch packs because it can cause tolerence problems and other sorts of mayham elsewhere.
I will shoot you a PM with prices concerning most of the parts he is offering you.

I'm not sure what shop labor rates are there but around here its anywhere from $50-75 on the bench.

Thanks for all of the replies. I'm going to tell him that I'm putting the rebuild on hold for now. I just bought for the family a ski boat and scored on a ford intercooler - $50.

CKT, Give me a month and I may ship it to you.

Also for the rest...Is it worth going to DTT and having it done there? They are a short drive for me?

It wouldn't be a bad choice.

Gunracer-PM sent

As for having DTT go through your trans, that would also be a good choice as they are a reputable shop. Just don't let them over sell you on things, for instance they will probably push a triple disc TC on you when a good quality single would be just fine. If you do decide to go that route just be sure to be informed on what you really need.
