Transmission problem
2002 Land Rover Freelander 6 cyl All Wheel Drive Automatic 70K miles

I have an 02 Land Rover Freelander with a transmission problem. Although only a couple times a day, when it needs to downshift into second gear it thuds. I have been told that third gear is not releasing rather than second gear not engaging. Instead of replacing the entire valve body I have ohms tested each of the solenoids. Some of them are high, but one is out of the range. The TCC solenoid measured 13.9 with an acceptable range of 12 to 13.2. I need to know if this measurement is out of spec enough to need replacement and if replacing this solenoid would fix the problem. The part is not expensive but getting to it would take a long time.

Hi me. Hansen, Welcome to 2carpros and TY for the donation

Did you came up with a P-Code 0730?

The TCC solenoid measured 13.9 with an acceptable range of 12 to 13.2. I need to know if this measurement is out of spec enough to need replacement and if replacing this solenoid would fix the problem.

I dont think 7 tenth of an ohm will make a difference replacement is not needed-the 7 tenth of an ohm is probably the wire resistance. The problem could be coming from a shift solenoid sticking-

No engine codes except P0171 & P0174 - Too lean bank 1 & 2. Should be an air leak.

I have researched what a TCC solenoid does and can only assume that if the torque converter was not disengaging correctly it could cause the hard downshift. But only when it down shifts into 2nd?

You're right. My multi-meter shows 0.1 ohms with the terminals touching. I was excited to find something out of spec. Plus the thought of replacing a solenoid for $65 and fixing the transmission.

I'm getting ready to sell the truck and want to try to get it fixed up as much as I can first.

Are there any other tests or relays or anything that I could look at to get it going again? I don't know much about Jatco transmissions but the fast, inexpensive fix is what I am looking for.

Lean condition: P0171/0174

Could be caused by one of the following:

Dirty or Inoperative Mass air flow sensor, an EGR valve that's leaking, fuel injectors dirty, low fuel pressure, pressure regulator leaking, PCV valve and vacuum
