2002 lincoln trans slipping first to second gear

by new do you mean new or used new. as a used new trans may have the same problem. if its new go back to the place you bought it from and see what they will do for you under warranty. did you get the original trans problem checked out at a trans shop or just assume it was the trans. it maybe time to have it checked out at a reputable trans shop.

Its the overdrive sensor 3rd gear you will slip with 4speed band trans
This overdrive gear setting if your sensor is not kicking in then you are due for trans maintenance as 3rd gear is shredding slowly away learned this from dirt track quarter mile super stock racing pray that your gear is intact as a trans shop with micro snake cam can only determine the length of time you have on your gears and trans inspections are free threw amco certified shops

P0507 Higher idle speed than expected partially stuck open thermostat engine running colder than normal raises idle speed. Small vacuum leak raises idle speed. sticking throttle cable holding throttle plate open.
P0741 Torque Converter Clutch system stuck off : Code conditions : No engine or transaxle system codes set, engine run time over 5 seconds , Throttle Fluid pressure switch not indicating Park/Neutral,TCC commanded On @ max duty cycle, throttle angle over 8% Trans fluid Temp input 68-248f Degrees not in fuel cut off, trans gear ratio indicates 2nd, 3rd, 4th gear delivered torque 32-150 ft lbs, the PCM detected a TCC slip value that was over the torque limits . most likely cause is bad tcc solenoid or torque converter itself. Trans shop can diagnose and repair

check fluid and if ok you have a pressure problem.
Check for trans codes, too

Hi there,

About the transmission slipping, which I have heard several complaints about, it might be an improper gear ratio code pop up and a gear slipping code popup. I would like to know in what gear it actually slips.

A common problem is also that the servo bores wear out and the servo piston gets cocked and breaks or the band just burns up.This could also be your gear ratio error.The fix is to drill out the servo bores and sleeve them. If you get an overhaul, which I believe any dealership you take it to would advise you to do, make sure they do that whether it needs it or not. If you can find a used trans that is extremely low mileage then I would buy it. A real low mileage trans will be very clean(bolts still shiny).

Hope this helps...

no , i dont think it will solve your slipping out of gear, call dealer or trans shop, they will usually check for free.

Get me the codes,for the data error.

I will try to figure out what your issues are.
May be the Digital Transmission Range Sensor, on the trans

You need a new Pressure Control Solenoid Body. 9L2Z7G391A -solenoid pack for a 5R55S Trans. $332.20. at Trans Parts supplier. Don't even call a Lincoln Dealer for a price. They wouldn't even deal with me because I have a sales tax ID, and ask too many question. They will screw you over big time. That's a common problem in a long list of LS issues, my wife has one also and I used to have a Trans Repair Shop. It will slam into Reverse cold, Slip or flair on 3 to 4 Shift. Also expect the EGR Valve to go bad and make the trans issue even harder to troubleshoot, untill it works correctly. Drop the tran pan, remove about 7 screws and change the solenoid body. Best bet, go to a trans shop, never a dealer. Also get the old fluid out of there and put Mecon V in ,with a bottle of Red Lubgard Additive.

you might want to have the filer and fluid changed in the transmission.

it either blew the trans or more likely there is not fluid left in it. look for a huge leak such as a cooler line or front seal leak. that whine is bad,its the hydro pump in the trans burning up, dont slip the trans! itll take about 30 seconds of that and its fried
