shift kits raise the line pressure to hold more power..... anything higher then that requires a custom valve body which is where im dreading haha.....

 

I was looking at Goerends tranny. But since I loke getting dirty, and other people are talking about building trannys It got me thinking. Never a good thing. Just today I noticed the tranny slipping more than I was used too. Went into thrid at 2K rpms, after ther shift fed more fuel and the rpms went up over 2K. The truck was pulling but man that tranny is getting sloppy.....

 

2 things i have done. enlarge the oil holes in the intermediate shaft. about .050 larger, takes a real good drill bit. make absolutely sure the trans coolers are clear. if in doubt install new ones. most of the od units are destroyed from lack of lube.

 

below are the directions for going to a 5/5 friction steel lockup over the stock 4/4


If you have a digital caliper measure the thickness of a steel and a friction together. I don't have it in my head but you will probably come up around 160 thou. If you machine off the thickness you just measured off of the reaction plate you will then be able to add another friction and steel. You will have to repeat this measurement/procedure for the overdrive as well.
This would give you a five count in each pack.
The OEM piston for third gear isn't the greatest and you may want to consider an aftermarket one if it looks warped or if it has distinct riding marks on it. Also if you have any doubts in the seals replace them

 

Cool, I got the FSm and will have to start studying it. I'm thinking I might get a core tranny and rebuild that one. As of now cant afford to have the truck down that long. anyone attempt this keep us updated!

 

i was looking at the kits that use a thinner steel and clutchs to fit in more friction plates/clutches.

 

Last time I checked, ATS sold a trans rebuild kit - comes with all your seals, frictions, bands, etc to make a super heavy duty trans - even has the machined pistons to fit the extra clutches. They also have a VB do it yourself kit. Going this route is very inexpensive, at least compared to buying an entire trans! Your only major purchase would be a converter of your choice.

 

Why don't you just use the 48RE clutch retainer? You can get 5 "full thickness" frictions and steels in there.

Just buy the billet retainer and apply piston and you can get 6 in there.

 

On second thought you can buy the DTT master rebuild kit for about as much as you can buy all the parts from TCS, or sonnax.

 

i guess i will have to go check out the dtt site, because that sounds intresting.

 

Does anyone have any concerns that there might not be enough room on the splined section of the input shaft/hub sections that a 6th clutch "might" drop off? The 48 RE holds 5 as Justin said and is working great in the last tranny that I did. Why worry about the OD OD section? It has a lot more capacity than the direct drum does, so the direct should slip LONG before the OD section will.



Give Dave G a call, that is where I get my stuff, hell of a nice guy!!

 

Will he sell a kit? I was looking to get a complete tranny from him, but I wouldn't mind building mine either.

 

Yes he will!!

 

i guess i should give them a call, it is not on the web page.

 

Thats what I'm going to do Justin. Either DTTs or Suncoasts and upgrade to a billet accumulator and billet servo.

Oh and Justin by the way, my bank account is getting close to the "money set aside for a TC" mark!
