Well i just picked up a 1995 PSD with 113k, E4OD, 4x4 , Long Bed Extended Cab. I have a problem with it. The guy told me it stalls sometimes....and he said his buddy said it was probally a sensor. So i figured it was a CPS sensor. Well drivin down the at highway speeds... about 60 - 70 mph the vehicle starts to shutter and lose power all the way until i reach about 40mph.Once i get back down to normal driving speeds the truck drive very good UNTIL sometimes at idle it will stall. After reading alot of forums and old school books im leaning towards the torque converter instead of the CPS just because of the 2 symptoms. Now before i take the Torque converter out and replace it i was lookin for maybe a second opinion. And i was also wondering if there are any electronics that i can test that control the Unlocking and locking of the torque converter. Any help would be GREATLY appreciated.
Torque Converter ??? HELP PLEASE

GOT PMS?
No, unless you have other problems I doubt that is it. It is very uncommon for the tcc to stick on, does happen but not common. Even so you would notice when coming to stops. Check the wires going to the IPR, if you look just forward and on the driver's side of the fuel bowl, towards the bottom of the high pressure oil pump resevoir, you will see the two wire connector on the solenoid. Check out the wires on it, (in a loom, will have to open the loom up) Diesel gets to the connector and wires here and makes the insulation all gooey then the wires short out to each other. Place to start anyway. Cps is alot of the times halfway predictable, this is usually not at all just quits when it wants.

i second the checkin the IPR comment.but dont completely rule out the CPS.the CPS does wierd things till it totally dies on some trucks.
That could be the probelm to the stall but what about the shutter. Let me also add the it doesnt do either ALL the time. Only sometimes. Ive expierenced it 2 times. Both times it stalled i was at a stop sign and both times i felt the shudder were on the highway between 60-75 and it went away at 40. Let me also add that the Vehicle was not hot when it stalled. It stallled at a stop sign just after leaving my school parking lot and it stalled 1 street down from my house. Ive had the truck for 2 days. Ive drove it on the highway 200 miles with no problems constant highway speed of 70. And i drove it to school about 3 times back and 4th ( 75 miles each way) Only on the 3rd time it shuttered. When i got home i checked the fluid it was low about a 1/2 quart i filled it. Then i took it back on the highway to the next exit and i was going 80 - 85 and no shutter , got off the highway and jumped right back on it did the same thing 80-85 no shutter. Went home drove it around town drove awsome. Got home parked it, got up in the morning and headed to school and on the way to school ( i didnt even make it 1 exit off the highway from my house) it started to shutter again. So i brought it home and got another truck. Then my dad took the truck and he drove it on the highway with no problem. Got off the highway then he got back on and he said on the way back it did the shutter with loss of power.
I found this too

ISSUE
Some vehicles with transmissions built prior to 11/13/95 (5L13) may exhibit a driveline resonance/vibration between 1400 and 2000 RPM with the torque converter clutch engaged. This may be caused by the torque converter.
ACTION
Prior to torque converter replacement, refer to the following Service Procedure for details to verify conditions.
SERVICE PROCEDURE
1. Verify the resonance/vibration does not occur in neutral and is most noticeable between 1400 and 2000 RPM with the converter clutch engaged during medium to heavy throttle conditions. Also watch for the vibration to diminish at engine speeds lower than 1400 and higher than 2000 RPM. If the concern meets all of these conditions and the transmission has a built date prior to 11/13/95 (5L13), replace the torque converter. Refer to the appropriate Service Manual for removal and installation procedures.
2. If the vibration concerns do not meet the conditions, check for non-factory installed items that could affect driveline and verify proper installation. Also refer to the appropriate Service Manual, Section 05-00 for diagnosis and testing.
****** I also read that the Torque Converter being bad ( or going bad let me say) can cause a Vehicle to stall at idle and shutter at highway speeds.
