: Transmission problems after HG fixed!!!

05-07-09, 12:04 AM
Well the car ran great for 1 week. Then, my dad was on his way home from work yesterday and the transmission decides it wants to take a vacation. Apparently in the 4 months that I had the drivetrain in the driveway (under a tarp and a tent) water got into the transmission fluid. I went to try and flush it out and found out that there is no flow at all to the cooler lines and there is no oil residue in there either, which tells me that the cooler wasn't in operation the entire week it was working (It's lucky that my dad works close by). I have yet to drop the pan and see what might be lurking in there. I'm not sure how badly the transmission overheated if at all but I hope I can fix whatever is wrong. I don't know very much about automatic transmissions, but I have a feeling I'm going to learn a lot very quick. My auto mech instructor was telling me that he thinks the pump went out or the pressure regulator valve got stuck while it was sitting and (apparently) collecting water.

But I want to know what you guys might think. Here are the symptoms:
-No flow to cooler lines
-If you open the fill cap/dipstick it will overflow if you rev the engine
-The tranny doesn't "jump" to engage any gear
-Every gear selection does nothing (acts like it's in neutral)
-With the engine/tranny cold you can get a little bit of movement but you have to rev the engine high in order to move the car slowly.

My instructor is going to lend me his pressure gauge. I read on the college's Mitchell program that there is a pressure tap port somewhere on the tranny. Do any of you know where that is? It says an adapter may be needed.

Same symptoms mine had when it was over filled.
It may be past the fixing point, unless you have a whole lot of energy. (And these transmissions SUCK to work on.)
A used transmission will run you ~$350-600. Might be your best bet.
Definitely was for me.

Thank you for your input. Can you tell me where the best place is to look for one?

05-10-09, 12:00 AM
Well I just dropped the pan... there's definitely some stuff in there that shouldn't be. I can't tell what it used to be from. It's very grainy, not fibrous, not very magnetic, and it smells like ash. Can you guys give any ideas of what it could be from?

It looks like it was underwater in a flood.

05-10-09, 03:14 AM
It kinda was... Complete downpour for 4 months straight.... Didn't have the tent set up the whole time either... this is also the same tranny that survived having a transmission cooling line rupture inside the radiator. I flushed 13 gallons of ATF through the tranny to get it close to normal. There was no way I could get all the coolant out.

Anyways, while the drivetrain was out I replaced a transmission cooler line that I damaged while taking the engine out...Today, after I cleaned up that pan and put it back, I disconnected both ends of that line and tried to blow through it. It was clogged. Something shot out of it, I dunno what it was. There were no caps or plugs on either end. So i think ultimately, the water isn't what killed the tranny. I think the clogged cooler line caused the tranny to overheat and fry some clutchpacks...

The stuff in the pan, I think it was disintegrated and fried clutch material...

I guess now I'm going to drop the cradle again... I'm thinking it would be a better idea to send it to a shop to get it rebuilt, or to just buy a new/rebuilt one. The problem is locating one on the Big Island of Hawaii. Freight to here takes months, and we kinda need the car sooner rather than later because we have family coming to visit soon.

Does anyone know what years are interchangeable with the tranny? is it just 96-99? The car is a 99 Eldo ETC, Vin: 9

There was some discussion awhile ago about interchange. I think the answer was any trans with the right electrical connector will interchange.

That's awesome to hear! thanks man! I'm not entirely sure what the plan is on this. I think we are planning to get this one rebuilt, but if we find a new/used/rebuilt one before we send this one in we will grab it and use that one.

All I have left is 6 cradle bolts and then the whole thing is out again.

05-12-09, 03:50 PM
I was looking at the FSM it says dropping the cradle is a 14 hour job. Last time I dropped the cradle it took me 3 days. This time it took me 7 hours... Now if i were only getting flat rate, it would be awesome.

05-14-09, 08:42 PM
Yeah - I imagine the second time gets easier - plus you are already primed for the task - you feel more confident because you already know what you're in for and know you can do with no problem. I dropped the cradle for my HG job, and wouldn't hesitate for second to do it again

OK, I got a rebuilt transmission in from TRC (Transmission Rebuild Company). They were actually my cheapest option after shopping around. Plus I got a good deal with them through my workplace, so it was cool. Around $1450 for the rebuilt and around $450 for shipping it here.

Currently I am having problems with getting the drivers side CV shaft disconnected from the tranny. Is there any special technique to doing this? The passenger side came out fairly easy. But with the drivers side, I am prying like crazy and doing everything I can think of and it simply wont budge.

The new tranny

The passengers side

The pain in the butt drivers side. I accidentally moved the strut in a weird position which squished some green grease out of the CV boot.

Does anyone have and tips/tricks for removing this CV axle?

05-26-09, 04:15 PM
When you are prying it, pry on opposite sides at the same time - you will probably need a helper. Prying on just one side can cause it to bind. I have not removed an axle from one of these before but I have had the same problem you are on other trans.

05-26-09, 06:15 PM
Wow, using 2 prybars worked wonders! Thanks man!


My next question; When I install the new torque converter, should I fill it with transmission fluid first? Or does it matter?

05-26-09, 09:12 PM
You can only fill it about half way. Yes, you want to put some fluid in.

05-27-09, 05:08 AM
I put as much fluid in there as I could, which happened to be about half way. Thanks Zonie.

A few more pics:

I plan on driving the car tomorrow... Hopefully everything goes together smooth enough for me to do so. :)

How did it turn out? Did the transmission "take"?

Oh, and thanks for the pics - this thread definitely goes in the bookmarks. I've got your car only a year earlier, so this might come in handy.

06-01-09, 05:07 AM
Actually I was stalled with other obligations, so I didn't get to test it yet. I will finish it up on Monday and post more pics also.

06-01-09, 07:49 AM
Sometimes one just wants to choke these engineers that design cars nowadays! Hope it works for ya!

06-02-09, 04:50 AM
Okay, it's all in and it all seems like it's running great! I test drove it, double checked everything. I'm getting no codes. No leaks either. I'm happy now. :D

Now for some more pics:

The new transmission cooler:

Sorry about how white some of the pictures came out. It was a bright and sunny day here. Tomorrow my dad will drive it to work and back and tell me what he thinks. I think it's a new car now. :)

06-02-09, 07:57 PM
Gah, it figures. Now I have some codes.

My codes are:
P0131 - Heated Oxygen Sensor (HO2S) Circuit Low Voltage Bank 1 Sensor 1
P0134 - Heated Oxygen Sensor (HO2S) Circuit Insufficient Activity Bank 1 Sensor 1
P0135 - Heated Oxygen Sensor (HO2S) Heater Performance Bank 1 Sensor 1
P0171 - Fuel Trim System Lean Bank 1

So it looks like I'm in the market for an O2 sensor now. Bank 1 is the rear bank (right side bank), right?

06-02-09, 08:09 PM
Hope not - I would not want to have to remove that one - especially not in the car!

06-02-09, 08:33 PM

Well, I guess I'll have to drop the cradle again... :rolleyes: lol

Actually, I've done it before on my 94... You just need a crowfoot for it instead of a O2 sensor socket. It's still pretty hard though.
