tranny problems.....help
Hey all. The other night I developed a problem with my tranny.
I have an 02 with 41000 miles,auto tranny, and 4.10 gears! 2wd also. No chips,mods, except a BHAF,bug guard, and a cap . OHH YEAH a baby seat Not towing anything heavy.
The other night while going around 50-55mph I had to hit the breaks quickly(GOT CUT OFF) and I stepped back on it but it seemed to lock up in 2nd gear. It felt exactly the same way when you put your auto tranny in D2. I was like what the heck. I pulled off the road. SHut the truck off,restarted it and it was fine. However when I started accelerating it feels like I was pulling 10K pounds. Once it gets going it seems to do fine. I let my friend drive it and he says it almost feels like the emergency brake is on or I am towing a big load.
However a new surprise happened tonight. I had to get on an off ramp so of course I drop my speed but then as I hit the gas to yield it wouldn't get out of 1st or second gear. (Actually similar to the first night of the problem.) Finally it slammed into 3rd (I THINK). Is this electrical or mechanical?? Sometimes stopping and restarting the truck seems to help a little. That is why I wonder if it is electrical.
I most likely will be taking it in for serv. Should I remove my Fleetguard BHAF and put the factory one on?? First problem ever with this truck. ANy help would be much appreciated. Thanks all.

The first thing I would suggest is pulling the codes to see if this trans behavior set anything. On-Off-On-Off-On and it will flash the codes up on the odometer.
I have yet to deal with a 47RE personally (I know my way around the 47RH pretty well though), but from what I understand ground problems can cause funny behavior, check and clean all battery terminals.
Sometimes the Governer selinoids/transducer get flakely and can do things like you describe.

I'm not sure where to go from here, hopefully someone else that deals with auto's alittle more will know.
Is your truck still under warrenty? If so and if your going to take it to a dealer I would put the intake back to stock just incase they gripe about it, some dealer might and other might not care.

sounds like a governor pressure sensor and governor pressure solenoid to me. i was getting second gear starts from a stand still and replaced those items and it fixed it, it's a real common problems with our 47RE trannys. works fine now.
keep us posted.
keep us posted.

JD thank you!
Ridiculous do you think it may be an electrical issue instead of mechanical?? Electrical to me would be more of the case as it does something different everytime I drive it. Where as if it was mechanical it would be the same problem over and over. Am I wrong thinking this??
I am no expert in this dept!

Mechanos do you mean putting the auto trans. lever into D2 or D3 and then you start the ignition?? Please forgive my NON Knowledge of this issue!

No, I mean when a trouble code is set in the ECM and it goes into "limp" mode. The ECM will cause the trans to start out from a stop in 2nd or 3rd gear instead of starting out in 1st. This is why it feels like your pulling a load when you're not.... the truck is starting out in 2nd or 3rd gear and is lugging the engine.

Tom, check out my thread from last year, You've got the same problem I had. It's the governor pressure solenoid. I got 90K out of mine before it went. It was a one day job. -Dad-

Thanks all
Well I meant to tell you all last week but I got too caught up with work!
But yes it was a Gov. press. sens.
$100 deductable and a $64 tow! Wasn't going to chance it!
One thing I noticed it seems to respond quicker(shifting into gear quicker) than it did before the problem! Is it me?? Or is it possible??
Not bad, got it in Feb of 02.......first problem so far!
Before you all say anything
Knock on WOOD!
