1G Auto transmission sluggish

[cruzer]

Hey guys, pretty new to this forum: 1993 Eagle Talon TSI AWD Automatic

My question is, have you or any other with these shift problems/automatic problems had any resolution because I just rebuilt my engine and had my transmission rebuilt by TMZ performance and I am having a really sluggish problem from a dead stop. The engine is running great at idle with no engine light.

But when I put her in drive she has no power. Reverse works great and when in Drive its sluggish up til about 2500 to 3000 then it gets power and drives normally.

Any ideas? Again, I have a rebuilt transmission with an AutoZone rebuilt torque converter, redline transmission fluid.

Also can anyone send post a picture of their connectors on the transmission. I think i might one or two on wrong because a couple of them look the same.

On a 13g you should have power by about 2 grand or so.

Not seeing any kind of tune or tuning device in your profile, I'd have to say your also on the stock auto ECU?

All those mods and no tune thats a

I am working on getting ECMlink V3. Need to save up some cash because the engine and transmission ate my wallet up. Got the LC1 wideband kit, but have not put it in yet. Wanna get ECMLink first.

Is the transmission even shifting? Sounds like its stuck in 3rd gear (aka: limp mode)

As for the connectors, match the plugs with corresponding wire colors.

Limp mode is what I'm suspecting. Limp mode has to deal with the TCU. You should still have 1st, and 2nd gear. As well as having reverse, that's also a manual gear. So putting the shifter in 1,2 and reverse all should work normally..

There is two different TCUs in the auto 1g cars. A 3 plug TCU and a 2 plug (plug meaning connectors).

On top of the auto trans there should be a connector with 3 wires. Blue, orange, and yellow with blue tracer. Make sure that's plugged in. As well as the connectors on the TCU itself which is behind the radio pocket. There is also one connector which goes to the shifter which puts the car into 4th gear(OD), so don't forget that one too.

So check the connectors first.Then try the manual gears, If 1st and second work normally.Your probably looking at just swapping another TCU, and the car should work normally.

Ok, so i didn't have a chance to mess with it today but i will check the plugs to make sure the colors match on both side of connectors and will check the connectors on my TCU as well.

As far as when i tried to drive it. I went through all the gears and they do move the car, just not very much from a dead start. Reverse seems to work the best with instant power, no sluggish symptoms for the most part. Again i will check the plugs tomorrow after work and see what i find. Thanks for the inputs.

Yes the transmission shifts, but only after i hit power which is around 2500 to 3000 RPM. Very sluggish up tip then, just seems abnormal.

Ok guys, your advice on the plugs worked. The transmission is working flawlessly with immediate response to throttle. Shifts great and all. Thanks for your inputs.

I have to tweak the timing because its missing a little. Haven't done that since the first start 2 days ago. Either way I'm not driving it yet either.

You guys have any suggestions on fuel pressure setting for FIC 750 CC injectors? I think i set it to 50 PSI for now. Again thank you for your help.

Until you install DSMLink (or edit the factory code) there is nothing you can do with the 750cc injectors.

When you do you'll need to decide if you want to run the factory base fuel pressure or the industry standard 43.5 psi (3bar) base and tell DSMLink you have changed the fuel pressure.

oK, sounds good. I will just wait until i get tuned before i mess with anything else.

For now i will ensure all the pre-requisites are done prior to tuning IE:
Checking boost leaks, Timing, Compression Tests, and all the other basic steps prior to ECM Link and Tuning.
