Reprogrammed Computer

Car Information:
Lexus ES300
Year: 1996
Engine Size: V6 3.0
Trans: Automatic

Issue/Question: Hi there, I enjoy listening to the show and am checking for a friend who is working on his Lexus. He is looking for a computer and is considering ordering one that, as I understand it, has been (re)-programmed for his vehicle. He thinks the computer is at fault because the transmission has to be advanced through the gears by moving the shifter. This is the second transmission to do this, he bought it from a junk-yard and changed it a few months ago. The cooling fan does not come on, the power locks don’t work or the factory alarm. These problems started after driving through a large amount of water. The car got a little better a week after the initial flooding but has not been right. Anyway, do you think the reprogrammed(?) computer will work properly? Thank you.

Answer:
Wow, depending on his insurance he would have been better off to have taken it to a shop and let them figure it out. If the engine runs ok, the PCM might be ok! He could be dealing with a bad transmission control module or relay and a bad convenience module and if that was the case those parts should be available used!

Problem Shifting

Car Information:
Honda Odyssey
Year: 2003
Engine Size: 3.5L
Trans: Automatic

Issue/Question: Problem shifting into 2nd gear. Trans waits longer than normal, then shifts hard. Doesn’t matter if it is an upshift or a downshift. If you drive moderatly, you hardly notice. Any more than 1/3 throttle and it shifts hard. You do have to baby it if you slow to 20 mph or so then accelerate again. It will shift hard down to 2nd. No problems in other gears. Was told I need a new trans, but if gently driven this one may last. Any info appreciated.

Answer:
Rich all we can do is replace the external shift solenoids and make sure the fluid is the right low viscosity. It does sound like a solenoid problem but their pricey from Honda.

Preventive Maintenance

Car Information:
Saturn SL
Year: 2002
Engine Size: 1.9L
Trans: Manual

Issue/Question: Do I really need to change the manual transmission fluid or grease? I have 133,000 mile. Also do I replace the gas filter? Its never been replaced. I say if there is no problems dont replace.

Answer:
What if the transmission fails because of worn out transmission oil or the car stops running because of a plugged fuel filter? That’s why they call it PM or preventive maintenance!

Dragging Transmission

Car Information:
Jeep
Year:
Engine Size: V6
Trans: Automatic

Issue/Question:
When the vehicle reaches 45 or 50 mph it ‘drags’ like a transmission that wants to shift gears, but with transmission trouble can’t. Someone said it was the transmission filter but the maintenance book doesn’t cover the topic at all. Can you help me? Greenway Jeep/Chrys. says it is ‘normal’ but a reputable jeep owner who generously took a ride with me said ‘don’t let them tell you it’s normal because it’s not. Can you help?

Answer:
Common problem, we replace a lot of governor pressure sensors on these transmissions for this problem! Bet your going through a lot of gas! If my suspicion is correct this can be replaced without removing the transmission, we can do the repair by removing the pan, If we replace the sensor, and the torque convert switch, service the transmission you should be looking at a little less then $500.00

Hyundai Transmission Trouble

Car Information:
Hyundai
Year: 2002
Engine Size: 4 cycle
Trans: Automatic

Issue / Question:
Periodically, the transmission or engine stutters. Then the transmission stays in 3rd gear and will not go into drive. The check engine light also comes on.

As soon as I stop and turn car off, the transmission is fine and check engine light goes off. The car shifts normally again. At that point, the transmission shifts fine and there is no slippage.

I recently had transmission coolant lines replaced and the mechanic added transmission fluid. He road tested the car and said the transmission was fine then.

A friend suggested that perhaps dirt in fluid was responsible.

What advice do you have?

Answer:
Something is causing the transmission to go into limp mode. The best place to start is with a scan to identify the codes causing the check engine light to come on. I wouldn’t worry too much about it until its scanned it may just be a position or speed sensor if it seems to operate properly when it does work.

Acura Transmission

Car Information:
Acura
Year: 1996
Engine Size: 2.5
Trans: Automatic

Issue / Question:
The vehicle recently started to take lomger to shift. 0-20 is fine but 20-40 RPM is hitting 4000 and over before shifting. I had the oil change in the transimission and lucas was put in there but no change. The vehicle has 205k on it! My brother in-law thinks it’s the vehicle speed sensor and transmission shift solenoid. Don’t want to change those parts for it does not resolve the issue. I want to make sure what the issue is and weigh my options. I also tried sea foam in the transmission but there was no change. It is shifting 1-2 as a side note.

Answer:
This vehicle uses an electronic shifted M1WA transmission. The computer system in this car ties the ABS, traction control and transmission shifting all into one big bundle of joy! Although you’re experiencing a late 1-2 shift it could be something other than a transmission or transmission control issue. We have seen wheel speed sensors cause this problem. If you have any other issues with this car we suggest fixing them first before spending any time or money on a transmission problem. Even though there’s limited data with the computer system on this car, a scan with a launce X 431 scan system would be where we would start. Make sure all other system are working properly first, then proceed with transmission diagnostics, if necessary.

Ford F150 Transmission

Car Information:
Ford F150
Year: 2004
Engine Size: 5.4
Trans: Automatic

Issue / Question:
I have a hard bumping at around 42 mph and again at 58 mph. It seems to only happen at slow to medium accelerations. If I accelerate through these speeds quickly it seems to go smooth. At such consistent mph/occurrences, it leads me to believe it may be a trany issue. Is there diagnostics you can do on these newer transmissions? It so what is the cost and what will it tell me. I just had the fuel filter changed and the transmission pan dropped about 10K ago. Truck has approx 120K.

Answer:
We need to drive it, as it sounds like a torque converter shudder. If that’s the case Amsoil ATF and Smart Lube modifier may be the answer. The worst case is replacing the torque converter.

Toyota Cressida Transmission Additives

Car Information:
Toyota Cressida
Year: 1980
Engine Size: 6 cycle
Trans: Automatic

Issue / Question:
The vehicle has 48000 original miles. It runs good but I have to warm it up at least 10 minutes before I take off. If not the transmission will not shift properly and it will slip. After it warms up it runs great.

Answer:
You may want to try one of the miracle transmission additives available at one of the discount part places. If that does not work its time for an overhaul. Seals are hard and won’t seal until the fluid gets warm.
