need trans. help quick....

[87_crown_vic]

i hae references about the place that say they know what they are doing. i wonder how much extra those few extra pieces will cost? i asked them if they rebuilt it if they can put heavy duty stuff in there.

It's an easy rebuild, to fuck up. Auto trannies require tight installation clearances. .040" is the difference between a firm performance shift, and a burnt up foward clutch in under 200 miles. See if you can find out anything on how these guys previous tranny customers have turned out. I'm not saying these guys can't do a good job, all you need is the book, and the tools to measure clearances. It's a simple step by step proccess (I've done a couple myself). But do your homework on the shop that you chose, trannies are something that some guys just can't seem to do a good job at (like the guy I bought my current tranny from, it's the 3rd tranny he sent me). BTW, if anyone is interested in all the parts for a 4R70W conversion, just let me know, since I have a complete second tranny sitting around. I'll let the parts go for a good price.

750 is a good price do it........have an a overdrive servo, a thunderbird supercoupe convertor and a transgo hp kit installed and you'll have a real nice tranny

the tranny shop wonders why certified transmissions charges double there price since they say it is an easy rebuild.

[Jason91GM]

thats cheap. i couldnt find anyone to rebuild mine for less than $1000 if i brought them just the tranny.

[87_crown_vic]

the clutches are burned up already. i took it to a tranny shop and found out that OD is slipping. i am gonna have to take it easy and drive in drive till i get her tranny fixed. it is gonna cost me $623 for it to be rebuilt unless i can get one that has been rebuilt and sent to me cheaper. it is gonna cost me $750 if i let them have the car and take it out and fix it.

[Blaze86Vic]

the girl needs to get over it, or pay for a new tranny.

Is it slipping when you press the gass in OD? If you have to feather it, you may have already burnt the clutches up.

I prefer more line pressure, but that's just me...

[87_crown_vic]

when she shifts into OD she falls on her face and makes the noise. i let of and feather the pedal to keep her going to stop the noise and keep it in OD. wish there was a panther mechanic to help fix this problem sooner that costing more later. hopefully i can straighten this out tomorrow. my g/f is getting upset w/ how i have been working on the car tryin to get this figured out. she knows i am pissed and getting fed up looking for the problem. but i keep at it knowing that it will be a great runnin beast when i am done.

Check the oil level in the rear too. It could be bearing noise but it shouldn't matter what gear its in, it would just be speed dependant. Sometimes you'll notice driveline vibration more in overdrive just becuase the torque converter is locked and the gear ratio is high.

[87_crown_vic]

since i changed the fluid in the pan, it only took 4.5 qts. i added to the bottom of the hatch marks where it states on the dipstick.
ok...i adjusted it and it shift into OD between 50 and 55. it is set at the minimum mark it suggests on the page w/ information. if i set it at mid it shifts hard and goes into OD around 75mph. had to bring it back down to shift where it was supposed to. does anybody think thjat the rearend could be the culprit. i drove on a empty blacktop road and got it to whine again. i turned my head and now sounds like it comes from the rear. i am gonna have another person drive while i ride in the backseat to listen where it is coming from. i did notice the rearend was leaking but i wonder why it only does this as it goes int OD. i will find out tomorrow. i am gonna pull the rear cover and reseal it and put fresh oil in it. i love buying new cars so i can work on them. keeps me away from the g/f wanting to argue about me spending so much time on my car. if it were her car she would be asking me to figure out the prob and fix it. so oh well for her. i wish i had the money to go to school for this work so i could make better money. oh well, just a dream.

[gadget73]

Thats the right fluid. You need more pressure, it shouldn't be in OD till like 45. For how to adjust it, check here: http://www.grandmarq.net/vb/showthread.php?t=2601

The whining could be the pump, or it might be low on fluid. How much did it take? Should be right about 12 quarts to read full when hot and idling.

[87_crown_vic]

i only drained the pan. it is dexron3 mercon. it says it works on all General Mistakes, and FORD automatic transmissions where dexron or mercon is used. it tries to hit OD around 35 or 40. how do i adjust the pressure? i hear the whining sound from the firewall when driving. i think it is in the front of the transmission that is making the noise like the torque converter is my guess.

[gadget73]

My car had one when I serviced the original tranny too. I was scared too, thought some part had fallen out of my transmission and it was gonna asplode. 126k of towing service left the trans fluid black as used motor oil, but it shifted just fine once it had fresh fluid. Completely amazed me. I'm sure it would have died eventually but I caught it on fire and made sure it was good and dead.

As for the shifting, whining into OD isn't normal. Whining in first and second is typical AOD behavior tho. If you're driving normal, how fast are you going when it hits overdrive? If its under about 45-50, the pressure is too low and should be bumped up a bit.

Oh, what kind of fluid did you use? And did you drain the converter too, or just the pan?

I found one when I did my tranny fluid. Just goes to show all departments don't maintain their cars, properly anyhow. :nonono:
