This is a very frustrating gremlin.

2004 4x4 screw 133,000 miles/Edge 2/Gotts/Efan/K&N

I've already replaced the TPS but am finding that the truck is still shifting at the wrong times. In regular driving, it shifts into 2nd gear at about 1600 rpm and drops down to 800 rpm. No power in that range. When coming to a stop, it seems like it does not want to come out of 2nd gear into first and almost bogs out. Now, it will die when shifting into drive unless I rev the engine before shifting in.

Can this be a torque convertor issue. I've always driven standard transmission vehicles, so diagnosing auto tranny issues is not easy for me. Can the torque converter be locking up early causing these issues?

Any help would be greatly appreciated.

 

Hi.

Any codes?

Does it do this with Edge removed?

(fyi - you can monitor TC lock with the programmer)

ab, your're not the first person to have torque converter issues with the Edge. The Edge is making the converter lock up early and sometimes won't release. Sounds like yer problem.

 

Thanks for the responses guys. There are no codes being thrown. I forgot to add that into the original post. I will be setting the edge back to stock to see if that fixes it.

If it is the Edge, I'll be putting it on Ebay.

What other options do I have to set the shift points for the larger tires? Can the dealer do it, or should I invest in an SCT tuner?

 

It may not be the edge......
What size tires you running and have you regeared?

What level tune you running?

Have you been doing some of the maintenance like fuel filter and cleaning the TB and MAF?

Also.....ever think of upgrading it to a Gryphon? It would be cheaper than a new SCT.

 

I'm running 325/60/18's but have already reprogrammed for the tire size. I'm running the Edge at level 2. I recently went through all the maintenance on it.

I know the upgrade is the Gryphon, but will that correct the Edge issues?

 

Check and clean your MAF I had a chunk of something get lodged in mine and it would over fuel the motor and stall.

 

Update on the Edge. I returned it to stock and it seems to have stopped the stalling issue, but its still locking in 2nd gear early and bogs down trying to downshift from 2nd to 1st when rolling to a stop. Wouls the next reasonable step be the tc solenoid?

 

Nevermind. Stalled again.

I suppose this is the torque converter control solenoid.

Problem solved...so far. In the initial test drive, everything is perfect! I switched the torque converter control solenoid and all is well.

 

do you have DIY

 

It's really faily simple and straightforward.

It's going to get a little messy. Prep by finding some way to cover the floor where you're working.

10mm socket
8 mm socket
extension
5 quarts Mercon V
Transmission Filter(may as well while you're down there)
Torque Converter Control Solenoid
oil catch pan
(optional)manual siphoning pump

1. There will be 14 10mm bolts to remove on the pan. Start working on one side. As the pan start to drop on the side you're working, it will start to drip. Be ready with your pan. If you have a siphoning pump, use it to drain off as much transmission fluid possible.

2. Carefully lower pan. Don't peel gasket off. It is reuseable. Inspect pan and magnet for big chunks of metal. remove and clean magnet of sludge.

3. Remove transmission filter. It's going to bleed fluid from filter and transmission. Be prepared.

This is what you will be looking at:



4. Carefully remove black plastic arm clip(not pictured). It is about 6-8 inches long and is attached to the prongs of about 4 sensors. I didn't notice any locking clips. I gently jiggled and pulled the clips at all the fastening points until it was released.

5. There is a 10mm bolt and and 8 mm bolt that secures the shift sensor to the tranny. You will have to remove those two bolts and the shift sensor. The tranny will bleed out when you remove that shift sensor. Be prepared.

6. Remove torque converter control switch. Just gently twist and bring it down. Tranny is going to bleed out again. Be prepared.

7. Reverse steps to reinstall.

8 Don't crush the gasket when boltiong down the pan. tighten until firm plus 1/4 turn. tighten bolts in criss cross pattern.

9. Refill Mercon V. Check fluid levels at 3, 4, and 5 quarts.

10. Start truck and idle for 1-2 minutes. Shift into each gear individually. Do NOT let your foot off the brake. I shifted up and down about 5 times.

11. Check for leaks.

12. Check fluid level.

13. Take a test drive.

 

Great write up!

Pix would really help.
