Hot trans questions

[hounddogs!]

After 30 miles on the highway, the trans is at an indicated 165-170F. Ambient is pushing 100. Let off for the off-ramp and coast without problems. As I get to the stop sign, I start to run rough until I pop it into neutral. Motor sounds fine at this point, but the trans temp has popped up to 180. Back into gear and pull away with a couple of serious stumbles, then things seem cleared out.

Sound like another one of the sticky solenoid / valve problems? I don't get this with in-town driving (under 150F). Also, it seems to have cropped up after the last trans service.

For someone who's not gone past oil/filter change on an AT, is this an at-home fix?

TIA

I am telling you..

Put a 700r4 solenoid in it. If you want more info as to why, call me at 916-739-0510 and I will explain in detail as to why. Trust me. I am sure Russ may chime in here too. Knowing Russ , he will go into detail as to why.

The 700 solenoid works in extreme conditions where the 200 doesn't. Far superior part than the 200 L/U solenoid.

PTS has a little test bench for solenoids and pressure switches. In the test, the 200 solenoid, under high pressure would not activate. The 700 activated no matter what, without fail, everytime.

If your replacing it, install the 700 solenoid. Cheap and easy to find/install.

Thanks for the input. Is the 700 solenoid a drop-in replacement? ie will I need to open up any holes, install spacers etc etc.?

 

[Russ Merritt]

2 little spacers between the case and the solenoid and connect the wires.

Thanks Russ. Are we talking 1/4" washers that are 1/16" thick, more or less?

Sorry I'm being neurotic. I'd like to do this right once and not open this thing up again.
