47RE problem, hanging in first
 

Never had a problem out of my stock tranny other than it slipping like hell when i do boosted launches but oh well ride er till she bucks ya fix it an go on lol but a couple days ago i hooked up to my trailer and my truck wouldn't change outta first unless i let off the throttle or i hit 30mph....thought it was maybe speed sensor or throttle cable...tried both and it's still doing it...i figured its probably a valve sticking but trying to figure out what would cause a valve to stick?...gonna drop the pan and VB this weekend and see if I can get to the bottom of it...also what would you guys recommend for a new VB I know ATS and all them are good but i'm not putting 600-800 in a VB i'm looking around 350-500 range because i don't have a whole lot of mods...maybe 325-350hp at most...also gonna do a TC sometime in march when work picks up...any recommendations on TC and VB and what might be wrong with it now :argh:

Govenor pressure is messed up

Yeah I was thinking of trying that next...do you know anyway to check for sure first though...will it throw any codes for that or anything cuz I don't wanna put it in an waste $120 if thats not it

No codes but if you know someone witha scanner that data logs you can find out desired vs actual and see what its actually pushing for pressure as well

alrighty well my buddy has a scanner that longs so I will try that I didn't even think of tryin it..nice truck btw

Governer pressure!!
 

Thats just what my truck did. It wouldnt shift out of 1st unless i hit 3100rpm, it threw a code but I dont remember the number, I changed the governer pressure sensor and solenoid, problem solved.

Do a Transgo shift kit or a DTT shift kit and a single disk(or a reman triple) Torque Converter and call it good.

Although I would recommend upgrading the servo cover and accumulator and Band strut and anchor as well. But they aren't absolutely needed. Just extra insurance.

Kazairl...I was just talking to a local trans shop and they suggested petty much the same thing. How much do you think a shop should charge to do what you suggested including the accumulator and band strut anchor? Just trying to get an idea.

The Torque Converter would be the most labor intensive because you have to pull the whole trans. The rest of it could be accomplished with the trans in the truck just by pulling the valve body. The shift kit is mostly replacing springs and drilling a couple holes.
So All in all Labor shouldn't be that much. Couldn't tell you a dollar figure though.

Ok, good...Thanks for the info.

hey thanks for all the input guys hopefully that gov. pressure sensor and solenoid will fix my problems....and thanks kazairl...i considered doing the same things myself but figured i'd go ahead and do a whole vb and be done with it...do you think it's worth the extra $ because really by the time someone charges you labor for the shiftkit and installing the other few parts it'd be about the same price as a new VB and I could install it myself

You could install a shift kit yourself too. Like I said, mostly it is installing different springs and drilling a couple holes a little bigger. The Transgo comes with some pretty good instructions. I've never used the DTT shift kit but I know their customer service is excellent. If you have any questions about what your doing then I know they will help you out.

Now, I don't think a shift kit will be as good as a valve body. There are probably a few tricks they put into a valve body that are too complicated to include as a DIY kit. But with a price difference of $3-400 it is up to you. At the power level you are thinking of running, I doubt it will make much of a difference. One of the things an aftermarket VB will do is circulate the fluid in neutral which can be useful in certain instances. I don't think a shift kit will allow that though.

Alright thanks alot man...I'm probably just gonna do the shift kit and try it out and see with that little of hp I don't think it will matter that much either but I'm gonna do a DTT single disc as well and upgrade the servo cover and accumulator and Band strut and anchor too

I plan on running 5-600hp on my shift kit. I'm no trans expert but I trust the one who built mine!! Talk to a trans builder.. I personally don't like dtt but I know they are helpfull to talk to..especially if they think your buying something from them!!! lol

To change the gov. pressure sensor and solenoid do you have to drop the vb all the way out? I heard you can drop the pan and change it without dropping the vb... I haven't had time to look at it yet and just wondering because if i need to drop the vb i need to make a tool to get the eclip out of the park rod

No you don't have to drop the VB to change the Gov. pressure sensor and solenoid.

ok thanks man...so just drop the pan and where is it located after I drop the pan?

After you get the pan off it will become clear, its really easy to get to, the worse part is getting it unplugged all covered in ATF.

What ended up being the problem?
