Cue " I wear my sunglasses at night. . " and the movie Dawn Patrol.

#1 in gears 1-2 At full throttle the cat will not go past 4300-4500 rpm. It will hover at 4500 and not up shift.

Does it ever upshift if you lift the throttle? If it will not shift up as you say it does, how do you ever get out of 1 st gear?

What do you mean by " goes into neutral " ? How do you know it is in 3 - 4 - 5 if the trans goes into neutral? Does the engine rev freely past 4500 when this occurs?

If you actually put the shifter in neutral during issue # 2, what would happen? If after this supposed neutralizing event, do you have to shut the car off in order to regain automatic shifting ( get it out of limp ) ?

At what % throttle does this shifting issue occur? If you reduce throttle slightly will the trans shift?

The farther into the throttle you are the later the trans will shift, this is normal. If the engine is down on power the RPM will hang and trans not shift.


Why 6 cans? How much does the manufacturer call for?

The shifting problems only occur when the kicksown is engaged.


When I say go into neutral, it seems the car is about to kickdown but it never grabs the gear. The kickdown is useless on my car.


99% throttle input is fine, but if I even try a soft kickdown it just revs freely.


The car never goes or went into limp mode. I need to shoot a video of what I'm experiencing.


First I'll check ATF level. I don't like throwing the parts shotgun, but kickdown switch and transmission 13 pin connector are going to get replaced soon. Those are my prime suspects.

Don't forget to grease the screw and threads on the spring compressor.

606 NA should upshift at 5500 or 6000 rpm at WOT

picture of my old W124 blocked tank strainer.

It caused the car to behave like a sloth. Once cleaned along with the tank. It had really good acceleration.

I essentially bypassed the tank strainer during the during the diesel purge.
I also bypassed any potential for clogged fuel hoses and lines.

The car behaved the same. So it's something else.

Still trying to get it to shift at 6000rpm?

lol

I was hoping to get my diesel purge today, but I won't because FedEx is the carrier. Running the diesel purge would effectively bypass the tank strainer if it where the problem.

You could do that without diesel purge if you wanted to see if that was your problem.

Your previous post says you want to run 6 cans. What does the manufacturer recommend?

They don't specify an amount, I just want to run it till it's clean and clear.

OK. I'd run a can or two then drive the car for a week then give another can. Sludge builds up over time and won't dissolve completely. The first cleaning will soften sludge then driving will clear some away. You will then be able to use a second can to continue the process.

Think of a bucket that has mud on the bottom. it can be rinsed out but some will be stuck to the bottom. If you let it soak for a while then rinse again, more will come out.

Yeah you're right

Appreciate the responses, but the more I drive it the more I'm convinced my transmission is dying.

1,2, and 3 flares a tiny bit. I'm still going to run a possible lift pump rebuild and checking the overflow valve.

If you put the shifter in 1st and toggle switch in " S " mode and you can't get the engine to run to redline ish , the engine is down on power.

Same goes for 2nd and SW in " W " ( in W mode the trans starts in 2nd )

Tried that, only goes to 4500rpm.
