ENGINE STALLS WHEN PUT INTO GEAR

1998 Lincoln Continental

Transmission problem
1998 Lincoln Continental V8 Front Wheel Drive Automatic 255K miles

When car is pulled into gear, the car dies, immediately. It idles fine and run great, until it is pulled into gear, the it stops running. Our technician ran the codes, found none, and told us the torque converter was staying in the locked position. He wanted to replace the transimission. I called a transmission shop, and they say it sound more like an internal transmission sensor. Has anyone ever run accross an issue like this? Any ideas?

Could be the TCC(torque converter clutch solenoid) also could be the transmission filter came off the suction tube. Also does it have working brake lights?

Merlin 2021, Thanks for the help, now a couple of more questions. Where is the TCC solenoid located, and why are you questioning brake lights? Thanks for the help, you guys are fabulous.

Torque Converter Clutch Always Engaged (Stalls Engine) Check valve body (bolt torque, gaskets and separator plate damaged or positioned incorrectly, valve body pilot sleeve, manual shift valve, bypass clutch control valve/plunger, solenoid regulator valve, converter regulator valve) and torque converter.
Brake Pedal Position (BPP) Switch
The brake pedal position (BPP) switch tells the powertrain control module when the brakes are applied. The
torque converter clutch disengages whens the brakes are applied. The BPP switch closes when the brakes
are applied and opens when they are released.

Brake lights work. First tech want to r& r transmission.
After road test, transmission shop owner says he is 85% sure problem in electrical. I did not care for first fellow, he seemed intent on transmission overhaul. He said that the transmission coded there was no electrical failures within transmission. He also said he unhooked the electrical to transmission and it was the same thing. That made no sense. We are new to this area, and do not know any technicians, that always makes it tough. Any suggestions as to what you would guess? Thanks, you have been great.

I think it could be either, what were the code(s)? The other thing is there is a wiring harness that runs in the back of the motor, wiggle the harness and see if it stalls. Has the pan been removed yet? Still could be the filter came off.

Mike the first fellow, said he ran the transmission on a " transmission computer". I had never heard of anything like that. He was not answering my questions directly and I felt he was trying to sell me a transmission. He did say that he " unhooked the transmission electrical, and the converter did not unlock. He did not pull the left front wheel off, and did not pull the inspection cover off of the transmission. He did not offer codes, and I didn't ask, he charged my son $85.00. We left.
The tranmission shop owner said he was " 85% sure the problem was electrical, and looked at our bill to see if there were any codes. There were no codes. I would have thought we would get a code or something. Our transmission shop charges $25 for the diagnotic test. He says if it is electrical, it should cost about $300 to repair. Your thoughts?

Probably about right for the shift solenoids. Check electrical connector at the transmission, make sure it's firmly seated, try disconnecting it, then inspect for corrosion, bent pins and do the same on the transmission, use a mirror to see the pins. Transmission codes are as follows and even a cheap hand held scanner can read them, I recommend you buy one, they work on all cars sold in the US since 96'

Odd that you ask about the code readers. Mike, I asked about the pruchase of one, and was told it was not a good idea. It had caused people to install parts that were not needed because they read codes that were not it the proper sequences.
I don't do a lot of work, anymore, mainly because I don't have time or understand it as well in today's world. I also own a 2008 Lacrosse Special (love those V8 engines) a 2000 F-150 4X4, and a 1966 Volkswagen Beetle. Is there a particular brand or type of scanner that you would recommend? I just checked on this a few days ago, because of the Lincoln problem, and was talked out of it. Any help you could lend would help immensely. Do all of the reader plug in under the dash, or is there a computer just for the transmission? Thanks merlin, you have been a lot of help.

Depends how much you want to spend, a very good laptop program can be found at autoenginuity, or cheaper hand helds at any parts stores, you can always read your codes and post them here with make model and year engine size of the car and we can help from there. Transmission codes are read through the same connection.

Thank, Mike. I let you know how this comes out.
I just wanted to say that I went to my first mechanic, I found him online, and he had the highest rating and the most responses. I think he might have posted them himself. Lol. I found the transmission shop, by accident, asking a professional parts man for a referral, because I was so new to the area. This has been a very good experience, I've learned a ton, in the last couple of days. Mostly, from you.
