Help! No Over Drive 4r70w...just installed tranny!

Hi,

I have searched, trust me I have searched! Expert knowledge in tranny problems requested!

I just installed a 40,000 mile 4r70w into my 1994 supercoupe. The transmission came from a 1994 or 1995 supercoupe that found a ditch. The tranny has been sitting for almost 3 years (stored in my garage). I cleaned the valve body which had some weird corrossion and drilled the mild setting in the plates. I also changed the 1-2 and 2-3 accumulaters (updated spring on 1-2 and spring removed on 2-3). I am using a 2004 Maurader convertor and deep pan with drain plug. Other than adding a large cooler and changing the lines to 3/8 SS, everything else was left alone. The MLPS was used from the "new" tranny because I saw that it had the gasket, where as the one from my original didn't.

The car shifts nice 1-2-3 but then doesn't even attempt 4th. Doesn't go to neutral, just stays in 3rd. OD button on or off makes no change. The car does engine brake when manually shifted to 2nd. I never messed with the OD servo or band because I didn't want to mess that up. If anyone has any insight to this problem, let me know. The tranny is acting like a 3 speed! Thanks in advance!

Is the OD light flashing?

Jay

These are highly engineered precision vehicles, the first step in diagnosing the problem is to strike the suspected offending part sharply and repeatedly with a blunt object, then re-test.

Did you swap the OD servo to the larger version?
If so, you probably missed the OD band....it happens.

No flashing lights. The OD light goes on and off when I hit the button on the shifter. I didn't mess with the OD servo...what are the odds that it could be bad just from sitting?

Do this.
Go put the car into drive and run it up to more than like 25mph. Then shift it into manual 1 and tell me what happens.

Okay...well this changes things...I don't have 1st or 4th. Manually shifting to 1st gives me second gear. What is going on?

Yes. Did you have engine braking?
It should have gone into manual 2nd and had engine braking until it slowed down enough to go to manual first at about 20mph.

Okay...I'll try that again...The procedure is to go about 35 manually shift to 1st, then engine brake down to about 20 to see if it hits 1st. I don't think it does that. I'll be right back. Thanks for your help...

No 1st. I've got 2nd and 3rd only. The way this car moves with the new convertor, I thought I had 1st. I've never had a good tranny in this car. During my drive, I went 30, pulled to 1st and waited, the car did not want to slow down. I drove around and found a slight hill. I slowed to 10 and nothing happed. Just second. I realized I didn't have first when the car did 75 without shifting, while locked in the manually shifted 1st position!

so it won't even start out in manual first if you put it there and then shift to manual 2nd if you move the selector?

When my car did this i found out it was Tranny fluid on the pins of the main harness for the trans.Seems the O-ring seal around it didnt hold up.

If what you are telling me is the case then it sounds likte shift solenoid 1 is dead or not being commanded. That will cause a no 1st or 4th condition.

Darrin, that's correct..no first, I tried manually shifting at 40 and no change...that should lock the wheels up! Would mlps do this?

I posted to another post on only 2nd and 3rd, I included the connector and what pins to test across for it.

After I did the JMod on my 97, second day I lost 1st and 4th. I ohmed it out and it was open (SS1), so I dug into it, took off the wires that connected to the shift solenoids, the harness ohmed out fine, the solenoid, then from the outside connector after I was done, and it was fine. I think I have 15k miles on since then and no problems.

Since it didn't ohm out from the harness I knew I needed to dig into it. It never set a CEL but I didn't drive it long like that, I figured I screwed up big time.

Story of my life, fix one thing, break two others. Replace busted intake, melt wires to DPFE and find out that if those wires cross the entire car shuts down, the cooling fan runs all the time, and the CEL never comes on.

I don't think this one is the MLPS. I think its a bad shift solenoid pack.

So do I drop the pan and switch my other solenoid pack in? Does it just unbolt?

Yup pretty much. There is one 10mm head bolt that holds down the shift solenoid pack and the TCC solenoid. Put your old ones in and see what happens. Cheap easy fix if it works.

well I did the following...

Replace solenoid pack- no change

Checked all wiring, even replaced tranny harness with original - no change.

What do I look to next?...It is 12:15, time to call it a night. Was really hoping that was going to fix it. Thanks for the help!

Well missing first and fourth, pretty much the only thing it really can be is that shift solenoid 1 is not being energized. You are going to have to find out why that is. It is likely in the wiring somewhere.
When you say yo replaced the harness, are you talking internal harness or external harness?

If you swapped the harness and the pack already and still have the issue...wow...it would have to be inside the connector or beyond. Make sure the harness from the car isn't laying on the exhuast or anything - inspect from there up. Like Darrin said, your problem now seems related to that solenoid and not the MLPS, but, you could try swapping the MLPS and see if that helps too.

You are on the right track so far.

I replaced the external harness. I will look into finding codes later. It is possible that this tranny isn't any good, some people in this world are not honest.

Is there anything that could cause this by drilling larger holes in the separator plates? No check engine light and no flashing od light. Could the 1-2 actuator be stuck? Would that cause no 1st or would it just cause no 1st to 2nd shift?

I don't have an extra ecu, but my old tranny shifted through all gears...my plan is to switch the internal harness. won't do that until this weekend. thanks, I'll keep checking this for ideas...

can you reuse the valve body gasket? It has only been in there for 2 weeks. I think I might check out the od servo.

Tranny fixed...for now...

Okay guys,

After testing all the wiring, switched solenoids, harnesses, I figured it must be mechanical. Drain the pan again, (I really like the drain plug), and then I swapped valve bodies. I put my old one in and I now have a four speed again. I don't think I messed up the drilling, so after I enjoy driving the car for a while, I am going to install the drilled plate onto the valve body in the car now and see what happens. Does any one have a clue as to what could be wrong with the valve body...it did have lots of corrosion, but I cleaned it really well, must have missed something. thanks to all those that tried to help. I'm glad to have the car back.
