(FL) 94 - Dragging the anchor
My problem is when starting off it is very sluggish. When going up my drive way (not that steep) it gives you the indication that the tranny fluid could be low because it slowly gets going (tranny fluid is not low). While my car is an automatic it feels as if you are starting a manual tranny out in second gear because it drags. I did the road test today and I believe my problem is I lost first gear. It does not start out in 1st from a complete stop - even if I click the shifter manually to 1st. There is no kickdown when you nail it from 45/50ish mph. Car has 125k on it.
My question...Could a B/G tranny flush correct this or rebuild necessary - Or ???
I know there is some theory about flushing the tranny when you have issues in that it could make it worse. Others seem to say it could help.
Please help me out ...

with 125k, I would bet the tranny is sick.
the 1994 tranny is the 4L60E, which is electronically controlled. So there is no mechanical governor.
Which leads me to beleive that the tranny is ill. Does the fluid smell funny?

My 94 when 3-4 blew out 1-2 still worked.
Put it in O-drive and hammer the pedel if it shutters or slips between 3-4,if she does, buy her a plot and a nice head stone.

How long have you had the car? What is the transmission service history?A few weeks ago i had transmission issues,and after having it serviced by a auto transmission shop,this is the information i have gathered from them about probable causes and possible signs to look for if left unattended. Due to the electronic control,the slightest hint of slipage will cause the computer to raise the presure to compensate,so the 4L60-Es dont really slip until they are very nearly dead (my 94 is in having the auto rebuilt as we speak) My clutches are falling apart badly, and the only sign of this in driving is a slight flare up from 2nd to 3rd at FULL throttle. The filter was chocka block full of clutch material,but the fluid was still pretty clean. This does not mean that some of this clutch material could not lodge in the pump or valve body in which case you may lose any gear if it does. If this IS your problem, flushing it wont fix it, and possibly the only way to tell if you have this problem is get a service kit and drop the pan,then cut open your filter to see what is inside.

Case outlined what I was aluding to... the electronic controls change everything.
I would limp it into a trust transmission shop and let them look it over. And don't be surprised if it's toast.

If 3-4 shutters and wont shift its the presure regulator.
If 1-2 shift bad trans bad.
I replaced mine at 90,000 and added a trans go shift kit.
Now it shifts the same as when I installed the programming to make it shift hard from hypertech.
Only $2700.00 to replace.

ONLY $2,700.00 to replace?? What country are you in??? Im in Australia and even going to the heavier duty 3-4 clutches (which gives you 9 clutches instead of 6) mine is only costing me around $2,450 and that is AUSTRALIAN DOLLARS... so i really hope youre not paying that in US dollars and calling it a bargain...

Yes I got ripped but! I am in Hawaii and here they love to rip you off, when they are the only game in town.
Yes US rip off dollars.
I got ripped for $1200.00 on my 700 r4 for my 86 US.
I also had to install a convertrer on my 86 for $699.00 Vigalante.
Total $1900.00 ripped off dollars US.
But when you are the only game in town that is the way it is.
But I have put the trans builder away 5 times in the last 5 mths at the drags.
I have made back $1500.00 racing so far this year.
I do get my way at times.

casethecorvetteman, I have owned the car for a year. Purchased from my brother that owned it since 96 with 23k miles at the time he bought it. The tranny service history only includes dropping the pan and has never been pressure flushed - not sure this would have made any difference??? My luck, it is probably on its way to being fried.

Mate, youre probably right there, i just had mine pulled out and rebuilt and the clutches were all burnt, the steels were cooked too, the sprag was buggered, and the bands were burnt. Presure flushing would not have helped at all. How often, i.e. what interval was the pan dropped and filter/fluid done? Should be done every 12 months or 12,000 miles/20,000klms. I replaced everything except the wiring loom and the planetarys in mine and the difference is amazing. BUT having said all that too, you may only have a bad electronic component inside. You really wont know till you drop the pan and cut open the filter. Mine was serviced, the filter was full of clutches, and in the 3 weeks i drove it around while i organized the rebuild it also half filled the new filter with the same kind of clutch material. This is in 3 WEEKS. So if you havent done anything about it yet, DONT leave it too much longer!! If you want a pic of what you are looking for, email me through this site and ill send you one. If you need recomendations on what parts to upgrade, email me!! I just went through it all and have all the info reguarding upgrades and what you need for what power output and driving styles.

Good point and thanks for the support. I would like to beef it up a bit but am at a loss to say where to begin. I will prob go all stock to keep it simple and not so pricey. I will get on dropping the pan and post my results. These posts should be relayed to the tips forum to help with future problems...
