 Hi all, I have what I believe is a 47re trans. question, so I'm a new owner of this truck and I'm admitting I'm more than a little nieve when it comes to transmissions. Anyhow, the truck seems to run pretty good and has a "built" trans. as in shift kit, beefed up torque conv. etc.. The prior owner said you have to kinda power brake it when it's cold or it dies when shifted into gear, said it had something to do with stall or? Well sure enough every time it sits overnight I have to go through the same ritual and then the rest of the day it does fine, idles fine, @750ish? Runs great,shifts great I've tried letting it sit and warm up for quite a while, but no, same thing like torque conv. locked up until it's revved a little in gear. I've tried letting it sit and warm up in neutral, tried pushing t.c.lock up button, no and nope? After going through the ritual I can shift into gear normally without insident. I have receipt for trans work so I decided to give them a call to see if this was in fact "normal" the guy I spoke with said it wasn't and never herd of such a thing! Maybe he's never herd of google? Because I'm coming up with page after page of people asking the same exact question! Some say it's normal some don't, really can't get any consistent answers. The trans shop guy said they don't mess with the stall and told me that they'd have to look at it, but it's like 300mi away, so....

  I really don't want to take to tranny shop if I don't have to, but? Any educated ideas would be greatly appreciated! Thanks!!

  • What "shift kit" was used? What is the stall speed of the torque converter?   VP44 trucks are notorious for not being able to fuel the engine quickly enough to catch the load of a converter

  • I've never heard of Freeman Creek Transmission in Orofino, and I'm only a couple of hours from there. Oh well, I don't know everyone.   Pressure is not going to stall the truck when you put

  • I do believe if the VP was starved of fuel enough that putting it into gear killed the engine that the VP would have already crapped the bed. The VP is heavily reliant on fuel for lubrication and cool

I think that is  vent.

Yes I can look at it but no guarantees we fix anything. 

 

Driving normal what rpm is it shift at?

  • Author

I haven't paid attention to the rpm's just know nothing seems unusual other than the first start of the day dying thing.

 Do you recommend I take that sleeve off and look at that cable? Just not sure of procedure or what I'm looking at.

 I do know my way around a vehicle but most my tools are geared towards the autobody industry I was in for 30yrs.

  I live around the airport area, maybe p.m me if serious about looking at, but don't feel obliged especially with viris scare, this thing can wait, your call.

  Thanks again!

 

The tv cable comes over the pulls tv lever to rear Has a plastic sleeve over the end that looks liking a writing pen body. It will pull off towards the motor with no tools.  Doing this will allow you to see and feel freeplay.

Tube may aslo already be loose

This is on drivers side pretty much under driver seat

Thanks Evan, I think you had some auto spelling going on there lol. So you check this cable in park, engine off?

There should be no play? Some? Tight?

 Thanks!

Never mind I'm looking at it in my Haynes manual.

Technically it shouldn't have alot of free play. 

 

The procedure to djust this cable is checking it at wide open throttle with converter locked in 3rd. Rpm when it makes the shift at wide open throttle should be 2800-3000.

 

Tightening the cable will make it shift higher rpm looser lower.

 

Theres is tv stop inside the tranny to set minimum pressure off idle  this is what I I am curious about.

Sounds like something I need to have a trans shop do? How would one measure that pressure?

Anyhow, the throttle and TV cable have similar slack in them, maybe both a little loose? Not sure what that upper inner cable is, that one is super slack. Cruise control?

 Thanks Evan!

No we can read pressure off the accumulator port in the the transmission.

 

I'll have to make up another gauge. Th he last one exploded in my cab when trans pressure broke 200psi. It's only 165 ish now.

 

Alittle bit ok slack in cable is okay. 

 

Would Wednesday work sometime after 5

That would be awesome! Wednesday works for me , let me know if you want me to come to you or would you rather see what's happening when cold?

 On a other note I got confused on that cable and checked from topside, will look again tomorrow.

 Thanks!

Hi Evan, so I just had a crazy experience.

I didn't realize I needed to check trans fluid level in neutral so I decided to recheck while cold this morning. After idling approx 5min I check and nothing on dip stick! What the?? So I drove around block and check again, normal level! I call trans shop and ask about, they tell me that's impossible, you can't make trans fluid from nothing, I say maybe true but that IS what happened, Them; no it didn't!

 Who's crazy in this scenario?? Any thoughts?

 BTW let me know if you need me to get a new gauge or anything else you need.

  Thanks!

Another thing, I checked that tv cable at trans and did seem slack to me, but compared to what?

Just got off phone with transgo to see if they could give pressure values on that, he said they can't without knowing kit# which I don't know. Described problem and he seemed confident there can only be two issues, restriction in cooling line or bad pressure valve. He did kinda give instructions on how to bypass cooler lines to eliminate that, so??

I've never heard of Freeman Creek Transmission in Orofino, and I'm only a couple of hours from there. Oh well, I don't know everyone.

 

Pressure is not going to stall the truck when you put it into gear, nor is a TV cable being out of adjustment. Set the TV cable for a 2900 rpm WOT 1-2 shift, and then leave it alone. And for the love of all that's holy, don't mess with the TV stop. That is set to a specific spec, and is not something to adjust.

 

Your engine is seeing a load large enough to pull the engine rpm down faster then the fuel system can fuel it to stabilize the idle. About the only things that the transmission could do to cause that would be a stall speed that's too low, or something wrong with the converter; incorrectly assembled, failed stator sprag, sprag in backwards...something like that. A converter issue will typically be worse when cold because the fluid is thicker. I would love to know what converter part number they used.

 

But, there's also the chance that the issue lies elsewhere.

Bingo!

Thanks for info, however since I have absolutely no idea how to do that, probably won't be messing with, sounds like it has nothing to do with stalling anyhow? The only thing I know about tv cable is how Haynes manual describes the1/32 end to end thing?

 So you wouldn't suggest bypassing trans cooler as suggested by transgo?

 The owner at freeman creek says he works on tons of dodges in area and has never heard of the issue I'm having, curious if you or anyone else has or am I an enigma?? As far as converter used, I didn't get a part# but he said it's a transtar billit triple disk, transgo diesel shift kit, sensors, sungear? So don't know if that tells you what you're wondering?

 Thanks for trying to help figure out!

You are jot the first to have this issue. I have read here of the issue in the past. Not many however. How to solve is way over my head.

I've seen this issue many times, and it almost always has to do with too tight of a converter.

 

I kind of figured they were using Transtar converters and Transgo kits, which tells me really all I need to know. I'm not trying to beat up on them necessarily, but I do deal with "local shop" builds a lot. It would be helpful to know what part number of converter they used. If they used an S4 or an S5, that's too tight of a converter. Believe me, I've been through the wars with those Transtar converters way back in the day, which is why I will only use specialty converter builders now.

Thanks dynamic, starting to think I just live with until I'm ready for new converter? Is there any harm to any components using this power brake  first start of the day procedure? Other than being annoying?

  • Author

Question for dynamic, so is their a way to loosen that converter or it is what it is?

Thanks!

Hey dynamic, BTW model of converter is or part# cacr70xs3 if helps.

Thanks!

So it turns out transtar operates right here out of boise so I call and quiz them, he called it a cascade low stall converter, (not enough to stall motor) he says best bet is to scan it and check lockup solenoid. Probably my next move after quarantine jazz and assuming we're all still alive!

Thanks, stay healthy!

Haha

 

I wanted to see if tv stop had been fiddled with. Are we locked down?

  • Author

Hi there, all I can tell you is I haven't messed with, locked down? Still your call I guess.
