Well,

I've been looking for a new transmission and today I got in my car and started it up to mess around with the sound system.

I was bored and put the shifter into first and guess what...IT WENT FORWARD...now I'm thinking what the hell is going on considering this is the same car that left me stranded and wouldn’t go anywhere at a light and it also went into reverse without a problem...

I'd like to get back into this car ASAP so I want to know, is there a possibility that the filter and fluid are just bad? I know the fluid is mostly black, it has only been changed once in the 200k miles that are on the transmission and there are no metal shavings or anything...I thought about dropping the pan but I don’t have a catch can laying around for it (that’s a lot of fluid).

I read somewhere that after a certain amount of miles on fluid thermal break down starts to occur where the fluid isn’t effective at such high temperatures or when it gets warmed up thus the TC or the transmission wouldn’t shift.

I thought about trying to take it around the neighborhood street real quick (no insurance) and I just got my AAA Membership but the thing was a pain to get up the driveway due to the Reverse not working properly (it would work when the car sat for a little bit).

It is possable ( and this is from the old days) that the screen/filter gets clogged from all the junk and gunk getting sucked into it while running causing it to clog. After you shut her down and let it cool, the junk/gunk drops back out of it, allowing flow till it gets sucked in again next time you use it. Food for thought :rolleyes:

Yeah,

Me and Big Pete are going to drop the pan and fluid Sunday and fix this beast once and for all...

I'M DONCING I GET MY BABY BACK! Hopefully it'll be the fluid and/or filter, frankly I don’t care as long as I can drive my baby again.

I used Lucas Transmission Additive (young, stupid, forgive me) and that’s when the problems started happening, it would fail to go into second gear and would go directly to third and fourth if I got it up to speed then that stopped and it worked normal and then it wouldn’t go anywhere one day and now its working again when its cold, when it gets hot though it wont go anywhere.

My dad was telling me about on his caprice (yes, I used to be poor in the 'hood) he had the same problem until he changed the filter and fluid...geeh thanks for telling me this when I dropped the money on the RX7 pops!

The fluid is BLACK/Dark Brown, there are no metal shavings on the dipstick tube, I'm going to wait until Sunday to drop the pan because I'll spill it all on me most likely so I need a better person to help me (Pete).

There shouldn't be any shavings on the dipstick, it's the wrong kind of steel. :D

But you may or may not find any on the magnet in the pan.

What usually happens, more or less, as the clutches wear, you'll get microscopic particles in the fluid that almost act like a friction modifier( if you will) that still works with the rest of the hydrolic system that still exists, (god my spelling s***s). It will eventually get to the point were it will start to clog (the system) up. It has been said (in the old days :confused: ) that when you change the fluid after an extended period of time without service (shiftes OK but fluid looks like s**t), you start to have problems because you lost all of the "MODIFIER" from the old fluid, which were the "shavings" from the clutches. You still should never see metal in your fluid when you check it. Maybe in the pan win it is dropped. I have had this happen to me in the past with an old Turbo 350 in my '70 MonteCarlo. It was shifting a little sluggish, so I changed the fluid in my drive way and it was never the same after that. I'm not saying this is your case, just thought I'd pass on a little personel experiance. :D

Well,

I'm getting my new transmission soon, avoid the above post and ignore it.

I do have something that's bothering me though so I tested my theory.

I turned the car on and put it in D, went up and down the driveway like a mad man when wouldn’t you know it, it did the same thing again after about 10 minutes of back and fourth, my guess was the fluid heated up and viscosity(I think?) of the fluids low because it burnt up when I power housed it when it first started acting up to get to work., just stopped unless I gave it a gas then it would slowly kick in and start going again (just like it did at the light).

Now, it definitely has something to do with transmission, the RPM's would drop real low and the car would almost die but I'm wondering if the car just needs a fluid/filter change and then it would be drivable to the shop to change the transmission out.

What do you think? Try and change the fluid, I've got about $500 to spend on this whole process and the trannys $240 so I'm down about to about $240 with the tranny bought and getting money's not going to be that big of a problem at the moment because all the bills are now paid (until next month).

you said the car would almost die. I assume you mean it would almost stop. It shouldn't bring down the engine any. I'd change the fluid and filter. If it is black then that would be my first guess. And shame on you for letting it get black and driving it like that. Bad, Bad boy, no doughnut..

Hey,

My dad owned it for the majority of the cars life, I just picked it up and was stupid and didnt do anything to it except think about car mods, not the mantience of it.

I've learnt a lot from TCCoA and I'm actually trying to stay off the streets race wise because of TCCoA, my dad looked at me like I was crazy when I said the car club restricts it! haha

Going to go buy fluid & filter and screw around with it!

Took the plunge and dropped the tranny pan by my self, next is the TC.







There was one little metal peice in the bottom of the pan (could of been plastic, not too sure) and the rest was little metal shavings on the magnet, really fine like I couldnt pick any up and look at it on my finger, only on the magnet when I swirled it around on the magnet.

Next the TC!

Yeah,

It wasn’t changed in about 90k miles! What do ya'll think, Bad enough to ruin the transmission? I'm taking an intermission to wait on Big Pete and my dad to get here.

That trans is junk, it appears to have been very hot and/or to have ingested dirty water.

It did get very hot, it first started slipping so I powerhoused it to get to second/third/od and burnt up the fluid doing so. The whole slipping started when I was sitting at a light about to play with one of my friends so I staged for a good two or three minutes on a 95 degree day without a trans cooler.

We'll see soon enough it works or not, if it does It'll give me some time to gain some more funds for a better trans than the marq.

Torque Converter is draining now!

PS, I overfilled the trans with lucas transmission stab - bad, that was the ultimate failure of it clogging the filter. The new filter you can stick a thumb tack through, this old one is almost solid clogged wise.

Alright,

Well, swapped the fluid & filter and it's doing the same thing it used to do before it stopped working, get up to 5k RPM before it shifts, I'm just going to leave it as is so it'll be able to make it down the driveway to get to the tow truck.

I just bought a 98 Mustang GT Tranny for $150 (50k Miles) but that's without shipping! :D

Would that effect the shifting? I know the filter is LONG over-due to be changed (by about oh say 200k miles - never been changed).

The filter must have been changed at some point, I do see a crappy cork gasket there.
