Things had gotten pretty frustrating for me. The 1990 Jaguar Sovereign was stalling in gear at every stop and I couldn’t figure it out. One mechanic told me to clean the Idle Air Control (IAC) valve. I did that but the problem persisted. Another mechanic suggest it was the fuel filter or fuel pump. That took care of the hard starting in the morning, but not the stalling in gear. What is going on!
As a last resort, I posted a question on the JaguarForums.com before I left work today. On the way home, the transmission was a bit more sluggish than usual. But it drove home well without any problem until I hit Liberty Street in Painesville. The car went into Limp Home mode and so I pulled over. There was no visible sign of transmission fluid dripping out of the car, so I drove it the last mile home. During supper, while the family was watching a DVD, I went out side to check the transmission fluid.
It was still warm from the drive home and after leaving it running for a few minutes was still halfway between cold and hot on the stick. But without a good plastic funnel, I was wondering how to add the fluid. That’s where the Raisin Bran box funnel came into play. (Hey, it worked!) I added almost a quart of Amsoil ATF before the fluid reached the correct level! Yikes! And now it doesn’t stall in gear at stop lights. After driving around town for a bit I came back to find the answer already posted. Thanks for the answer and link to the TSB. Now all I need to find out is how to get the car out of limp home mode. Any ideas there?
