  1. 4R70W Transmissions
    About a year ago I had changed a leaking transmission gasket and has put ~6 quarts of dex iii/merc in it. I have since driven about 5000 miles and the other day I was in 3rd pushing 85-90 uphill when I smelled something burning and I let off. The transmission fluid was still red but smelled...
  2. 4R70W Transmissions
    I have a 1996 Thunderbird with a v8. Between 2-3 and 3-4 when i ease off the throttle during a shift the whole car shutters for a second, as if its going over a sudden bumpy road. Yet at the same time it never shifts hard or slips, not even at higher rpm. My mileage is 217k but the car runs like...
  3. 4R70W Transmissions
    I drive a 97 Thunderbird and I disconnected my battery to redo the positive cable because it was super corroded. I reconnect the battery and now my car is shifting weird and way too often. It feels fine when I am on the gas but when I let off it does something in the transmission feels and sound...
  4. 4R70W Transmissions
    First time posting so I’m not sure how this works but I’ve got a 96 F-150 with the 302 that the trans blew up in and I got a new one from a buddy of mine that came out of a 96 Mustang GT 4.6. They look to be the same trans but the new one won’t fit up right. Is there anything I can get to make...
  5. 4R70W Transmissions
    So I started this with my 97 cougar xr-7 with the 4.6. Car has a prob 200k on it. I just did a filter kit with fresh mercon v. All went smooth. No leaks. Before the filter kit I started getting weird shifts. Mostly just 1-2 but reverse felt awful and sometimes 2-3 would be hard shift also. I...

    Hi everyone! How you guys are having a great day! My 2009 P71 Crown Victoria is having a really weird transmission shifting issue. I noticed it last night when I was driving home from my parents house. The car starts and runs perfectly fine, however, when I put my shift selector in Drive, the...

    SO, here's my problem: I just swapped in a 97 4r70w I got out of my junked tbird into my crown vic after having issues with the original vic trans. It started out amazing, then the next day it started to slip progressively worse and worse, then the next day it wouldn't even fully engage drive...

    I am new here but I am totally lost and need help. I am working on a 2000 expedition transmission. It is 4r70 doing a total rebuild because one of the clutch piston seals went out. I got the full rebuild kit then pulled everything out, inspected and cleaned it all. I have rebuilt transmissions...

    1996 Ford Thunderbird 4.6L Torque Converter Original posting got deleted for “spam” So I have a 1996 Ford Thunderbird 4.6L that I’m ready to go all out in building it to where I’ll eventually swap in a 5.0 Coyote engine. Car is currently bone stock. I’m J-Modding the transmission(75k miles)...
  10. Stick Transmission Swaps
    I have a 95 Merc xr7 with the 4.6 with I believe is a F1AE or the F2VE casting. I also have an M5r2 from a 300 I6 out of a 96 f150. Will this unit work on the 4.6? If not, what do I need to look for?
  11. 4R70W Transmissions
    I've read a lot here about turning off the overdrive in town to prevent frequent shifting. How frequent is normal? If I'm going 35 up a hill (for example), and it's just the right grade, is it ever normal for the transmission to immediately switch back and forth between 3rd and 4th gears-pretty...
  12. 4R70W Transmissions
    Hello all. I've been putting this off but I'll try to explain what my transmission is doing in my '97 T-bird 3.8. I've searched the forum to no avail trying to find a solution. From a stop it shifts fine from first to second. If it's cold outside it shifts slowly (like someone slipping a...

    Hello, I have a 1994 Ford Thunderbird LX 4.6 with the 4r70w with 96,000 I suspect that the Torque Converter Clutch Solenoid (TCC) or the Shift Control Solenoid have gone bad. I am experiencing delayed upshifts at high RPM from 1st 2nd and from 2nd to 3rd. If I manually shift from 1st to 2nd...
  15. 4R70W Transmissions
    I think I made a terrible gouge in my trans pump cover when removing the seal. Its an 05 f150 4.2 V6 automatic. Can anyone tell me how bad I fudged this up? or would the new seal cover it and prevent from leaking? fingers crossed. Also, this truck has the 4R70W transmission in it. I have only...

    Hi everbody Transmission (98) died on my F150 and I found an used one (97) for a fair price. I found I found some information on this website, still have some doubt I understand some update has been done on the 98 and understand clearly how to swap a 97 with an upgraded 98. But I am in the...
