I'm not sure of which forum to put this in, carbs or tranny, so I'll put it up in both.

Anyway, I recently swapped my computer-controlled q-jet, for a non-computer controlled Edelbrock #1405. I also swapped in a rebuilt non computer-controlled HEI distributor. It's a vac. advance set up.

The car runs great, however, my torque converter lock-up isn't wrking now due to the lack of ECM controll. How do I fix this??? Any help would be great..
P.S.- It's a 700r4 tranny..

Thanks

 

I think you would have to get a lock up kit,i just got one cause i swapped my tbi to carb but I didn't get a chance to put it in yet here's a part # if it helps,TCI makes it and the part # is 376600it's like $75 though.

 

Thanks, I just called up Summit, and they said get the sam kit..

 

You can hook up a manual lock up switch to the ALDL box below the dash if you want to save money!! You just have to remember to turn the lock-up off when not in OD because the car will be "sluggish" in 2nd and 3rd if you don't! I thought about buying a B&M megashifter for mine and then buying the B&M handle with the switch on the side and wiring up the lock-up to that switch!! But I'm stayin' with FI afterall so I won't need too!! Just an idea!!

 

Remember, since he isn't using the computer, by-passing it via the ALDL will not work, he has to get a kit, which he has done

 

As long as you haven't torn out ALL the wiring under the dash, the ALDL connector can still be used to lock the TCC without the computer.

 

I haven't ripped out the wiring, because I haven't decided on the final plans of the car. Anyway, whats the easiest/cheapest way to make my tranny work. It seems to drive ok now...but it's VERY sluggish off the line and through thirs gear. But that's the way it's supposed to be I guess.

Any suggestions appreciated.. . . thanks...

 

I've got the TCI kit, and it works fine. It has some annoying in/out engagement of the TC at light throttle in 4th gear sometimes, but it's not bad. Thats what you get when trying to control the lockup by vacuum instead of a computer I guess. I tried tweaking the setting for it (finally uncovered adjustment screw) and I've had a heck of time just getting back to as good as it was before I messed w/ it, lol. It's damn sensitve...

Anyway, it works. And you don't want to be driving around in 4th gear without locking up the converter, either manually or via something similar to this or the $130ish B&M kit. It will run hotter and can screw stuff up if you don't keep it all cool w/ a aftermarket cooler...

Is the tranny signal line hooked up to a vacuum source on the carburetor?

 

The easiest/cheapest way to do it is to wire a switch to the pins in the ALDL connector so you can manually lock the converter when you start cruising in OD. The best way is probably to use a vaccuum switch kit like TCI's.

 

Assuming you were talking to me regarding the TCI kit dsmanimal, then yeah. I have it hooked up to a ported vacuum source on the carb.

I got the B&M kit so that i can control the mph that engages in and it is electronically controlled. it cost $130 i think someone already mentioned this kit.

How do you like that kit super83Z? How is it when you start to lightly accelerate while the TC is locked up, does it unlock as quickly as you'd like? Smoothly? Does it have a tendency to lock back up almost immediately, or does it function about right? Just wondering...

What happens if you dont wire a lockup switch. I pulled the carb and distributor but havent wired a switch yet as i am thinking of going to a th350 or th400.

will it hurt anything? i cant afford a new trans for a month or so.

i got an 84 camaro, shes got a 89 mustang. which do i have to work on more?

 

i run a non lockup stall converter and never hooked up a single wire

Using a non-lockup converter in an OD trans with mild rear gearing will cause rapid trans failure due to excessive heat unless you put on a decent sized trans cooler. Remember that cruising in OD at say, 60MPH you are CONSTANTLY below the stall speed of the converter and that means slippage which means HEAT.

If your car is "sluggish" then I would look at the tuning of the carb and the advance curve of the distributor you just installed before blaming the loss of lock-up converter capability. My experience is that it "feels" just fine without the lockup, all else held constant.

 

good point, trans coolers a must in my application. i have 8000 miles now with no problems. i do know someone who disconnected the lockup without changing convertor/ or adding a trans cooler and his trans was very short lived.

I just said screw it and i put in a turbo 350 w/ shift kit, its stonger and a hell of alot better. Got rid of my shifting problems, now to get my other problems, thats a different story

thats ok if you don't want OD. But I personally want OD.
