Hello, I am having trouble with my 1994 6.5 TD transmission. My car will rapidly shift between the lock up, 4th, and 3rd gears for a couple of seconds then a service engine soon light will come on then it will stop for a few minutes and the service engine soon light will turn off the gears will start rapidly shifting. I just changed the shift solinoids and put new oil and filter in the transmission. If any of you know how to fix this please let me know. Thank you

And shift speeds as well as 4th gear can be affected by engine temp. When it reads below 44 degrees I believe it is, it disables 4th gear. So it sounds like you've found your problem.
