was there any parts underneath the valve body that should be replaced that don't come in this kit?

That sucks Adam, but all it cost you is your time. Always do the free stuff first. up

I'm surprised that check engine light came on so quick, did you even put it in gear or try to drive it? Is there any change in the code list?

The light coming on immediately indicate an electronic problem. What codes came back?

All the parts in that kit can be replaced without removing the valve body. You just need to drop the pan. I believe there some overdrive solenoids that require you to remove the valve body. I didn't replace these as they are not as common a failure item in these transmissions. I'd just do the easy stuff first and install a drain plug in your pan in case you need to drop the pan again.

Hate to but n but after each time I start the engine the overdrive off light is on, push the button light goes off, what's up?

Ok sorry for delay, I rechecked the codes and they are all still there, plus a P0441 EVAP Purge Flow Monitor Fault

P0753 A/T 3-4 Solenoid/Transmission Relay Circuit Failure

P0743 A/T Torque Converter Clutch Solenoid Circuit Failure

P0720 A/T Output Speed Sensor - Low output Above 15 MPH

P1764 A/T Governor Pressure Sensor Signal Too Low

P1765 A/T Transmission Relay Circuit Malfunction

It still kinda bothers me that my trans relay has 5 prongs but sits in a 4 terminal slot, so basically the middle prong doesnt connect to anything. Could this be the wrong relay?

I think Im going to order the complete solenoid kit from cascade, that way when I drop the pan, if there's no mess, Ill install it, if there is a mess, I send it back and look at rebuild options. I know this is not the most graceful way to handle the problems, but these parts in the kit are the culprit in so many of the problems with the RE transmissions that Im willing to bet the kit solves my issues.

Sounds like a plan, I've read into solonoid pack replacement but so far have not had to do it on my RE.

When you get it drained, take out the output speed sensor and clean the tip. If I remember right it's a small magnet and bits of metal will get to it. That may be why you are getting that code.

Don't take it out before you drain it........or you'll get a bath. Damhik.

Ok I ordered the kit, it arrived, I unhooked the negative battery cable and dropped the pan. Fluid was clean and the magnet had barely any gunk on it.

I installed the 46RE Governor Pressure Service Kit 2000 Up from cascade.This included the governor (governor pressure transducer), the shift solenoid (governor pressure solenoid), the gasket for the housing of those 2 units, the 3-4 accumulator spring, the tail shaft speed sensor, the new filter and the new pan gasket. Filled it with atf+4.

I also bought a mid grade code reader.

I hooked up the battery and fired it up. Within 10 seconds or so, the check engine light came back on. I cussed and got in and took it for a ride. Again, when put in drive it starts out super slow and I figure this either means it’s starting out in third or something is wrong with the torque converter . But before I could only manually down shift to second and it would never going to first and also overdrive was not working.

This time again when put in drive it started out really slow just like before But this time I could manually shifted into every gear first second and third but I didn’t get it going fast enough to see if it went into Over Drive. When put in the first it kind of feels like it doesn’t catch until you give it a fair amount of throttle but nonetheless it went in the first and second and third manually.

First read of codes: P0743 TCC solenoid circuit, P0753 1-2/4-5 Solenoid circuit, P1764 governor pressure sensor low, P1765 1. Switched battery failure 2. Trans power relay circuit

I cleared the codes and turned it back on, again the check engine light came on in about 10 seconds and I took it for a drive. It seem to drive a little bit better.

Second read of codes: P0743 TCC solenoid circuit, P1764 governor pressure sensor low, P1765 1. Switched battery failure 2. Trans power relay circuit


With one of the codes disappeared, I switched out the trans relay with another relay and no change. I’m starting to think I have a short somewhere. I have heard of the downstream O2 sensor Circuit causing short problems as it runs in the same harness as the transmission wiring. Or maybe my TCC solenoid is shot and I should’ve bought the full kit that included that!!!

What do you guys think? What should my next movie?

I think the next move is:

1. Manually shift it, drive for a bit, get some miles on that fluid, let your new filter catch what it can and do it's job. You say you have'nt been in 4th yet: make an excuse to go for a road trip. Your tc locks in 4th (and will in 3rd if you press the "overdrive off" button) and needs to get run in top gear for some miles. Give us an update.

2. Change the tcc solonoid-I really think this is the problem now. I think that's why it's dragging it's ass when you take off: t/c not unlocking, solonoid burnt.

3. New torque convertor.

4. There's a transmission in Portland with 132,000 miles for $830.00.

Like I stated earlier - you have circuit failure codes, fluid and temperature has nothing to do with these codes.
Look the harness over real good for chaffing or damage. From the controller down to the trans.
Carefully pull the connectors loose and clean and inspect for corrosion, both the female and male ends.
Switched battery failure stands out like a sore thumb.
It's dragging because you are in default third gear. If you can pull it in to low and it accelerates like it normally would that confirms default/third gear start.
Converter has nothing to do with your problems at this point.
And yes the O2 circuit can wreak havoc on trans controls due to the sharing of the harness at the splice.

Where/what is the ‘controller’?


Is it a bad o2 sensor or bad o2 sensor circuit that causes the problems?

PCM - powertain control module. Controls the engine and trans and receives inputs from many sensors, like the O2 sensor, RWAL sensor etc. I would have to find my manual to help you further but I would work backward/upward.

Start at the trans external connector (round connector - enters the trans on driver side behind shift linkage). Be careful taking all these connectors apart and putting them together as some of them have very small pins and are easily bent.

Work your way up. PM me if you hit a road block and I can try to send you some screen shots of a schematic.

I know the connector you are talking about, I’ll start there. I know where the PCM is I just have never heard it called a controller so that’s why I asked. But it is obvious someone has cut the pink wire out of the middle connector of the PCM and At the relay box and jumped it. I don’t know if that has anything to do with the transmission but I’ll find out as I trace these wires

The plot thickens.

Still looking for my manual - I may have loaned it out.

Yeah.

You failed to mention this. smirk

Get this issue looked after first.

I just went through every wire underneath near the transmission from the O2 sensor rear to the neutral safety switch plug to the circular plug above the shift linkage.
I could not find any broken corroded or worn out wires stripped back all of the sheath and wrapping on everything all the way up to the side of the bell housing where I could not reach any further.

The main circular trans plug is in good shape but the connector it plugs into that’s coming out of the trance has some snapped plastic but as far as I could feel the pins were all intact and straight so they plugged together just fine.

The pink wire that runs between the PCM and the relay box that’s been Cut both ends and jumped is something I just noticed actually.

Something that I didn’t even think to mention though because it did not show up on the codes and I thought it was just a fluke, Is that the ABS and brake warning lights on the dash are always on. Once in a while they won’t be on when I turn the engine on but 95% of the time they are on.

While researching my codes and issues I came across the thread where someone was talking about replacement PCM’s causing the ABS and brake light to come on unless they’ve been flashed with the vehicles Vin number. So it looks possible that the previous owner had some PCM troubles and jumped that pink wire for some reason and probably switched out the PCM At some point as well

It's messy but you should drop the pan and check source wires inside the trans against their matching wire in the top connector - I have seen enough carnage on the outside and inside harnesses. If I recall the main power source to run all the internals is the center line in this connector - if the voltage is low there then it's all low.
