4.11 swap weard shifting

jeffast · #1 05-02-2007, 02:38 PM

ok so i got my 4.11 trannie in and it runs and drives great, but it keeps shifting constantly, i'll be going down the freeway down hill with out giving it any more gas at 65 it will randomly shift into third then right back out. it does this constantly regardless of gear it seems to only do it on odd speeds though like 55, 65, if you going 60 its fine, if your going 70 it's fine, go 75 and it will keep bliping back and forth with no regard to what you do unless you eather accelerate to 80 then it stops, or put it in 3 and leave it there, do i need to put a 4.11 tcu in to get it to quit, any ideas?

Two things;
-They recommend a different resistor to be used with the 4.11. This is the one behind the battery box. Do a search, if you can't find the info, send a PM to "svxfiles"

-Check your TPS

cool i know the one you mean do you know where it is in the legacys?

Ditto on both. svxfile's resistor works (I have it in my 4.11 92) the shifts are a bit firmer than stock, but very clean. Also had to adjust my tps a hair to make the shifts smoother. So far Ive put about 4-500 miles on it with no mishaps (Well...had to put a new cotter pin in the end of the shift linkage.....and had a tranny line split...but no actual shifting problems)

I'm not sure where it is on the leg's and mine isn't here to check. But, I'm also not sure if the leg has the resistance that Tom suggests???

ok, how do i check the tps.
i unplugged the resister and drove around for a bit it seemed about the same, but it still jumped in and out of fourth at odd speeds, do i have to adjust the tps, how do i do that on an svx?

In the "How to's" up top.
engine -> TPS

Go to my locker and you can read up on both TPS testing and how the resistor operates.

Your problem would appear to most probably involve the TPS. Testing and setting this component, is not a highly time consuming, or particularly difficult task.

You have used good sense in running a test to eliminate the resistor from the equation.

stupid question, i can't seem to find the how to's, or figure out how to acess peoples lockers.
thanks this site and the people on it are awsome!!
EDIT: i'm a moron i just saw it thanks

Clean the TPS sensor and reset it to .52 volts. Afterwards, Unhook the battery for a half hour to reset everything.

Check the top of the page, to the right of the SVX logo, select what you require and click on it.

how do i know where 5.2 volts is?

Hocrest · #13 05-02-2007, 09:17 PM

It's all in the "how to doc's"

Do you have a voltage meter?

yes i do, which slots do i plug the meter into?

the write up just said the plug at the ecu??

Ignore the ECU comment in the beginning. He's talking about the connector going into the TPS in the following description.

Stick your pin right through the white insulated wire so that you can clip your meter lead onto it to make measurements. A fine pin will not damage the conductors as they will spread and there will be no significant damage to the insulation. Measure between the wiper, i.e. white wire and ground, by connecting to engine, chassis, battery negative, or whatever.
