420A 1999 Eclipse Gs Auto Trans

[Thomas Mason]

Pretend for a second, you have a 1999 Mitsubishi Eclipse Gs with a auto trans. Now pretend that 8-10 times you start it, or more, it doesn’t shift gears. When not shifting your limited to about 55 mph at high rpms. When it does shift, it does so smooth and never stops until you turn the car off. When it shifts it shifts, when it doesn’t, it never starts shifting while driving. It’s either on or off... where do you start?

personally, i would start by pulling out the auto tranny and getting rid of it. a 420a with an automatic transmission is so NOT fun to drive, just thinking about makes me wanna walk out into traffic.

The valve body/solenoid pack on those transmissions go bad frequently just as your describing, they are fortunately replaced from outside the transmission easily, maybe grab a junkyard one from a clean crashed vehicle and try it out.

Thanks motto for having the only helpful mature response. Unfortunately a trans swap isn’t in my budget or realistic abilities considering I have 4 kids and work as much as I do. If I had that option I would just be in the gsx tuned out that I’d like to be in. I actually have a rs also so maybe said solenoid can be switched out, if I can find it, and I’ll see what happens. Appreciate the help that some of us count on in these forums though motto.

sorry but you should expect that kinda response when you say to pretend.

damn, you know what i just thought of.
those 3g transmissions have a shitty wave ring that breaks apart and grenades the trans.
i had to have the pump replaced after installing the engine with the torque converter not snapped in all the way. I had the wave ring replaced with the redesigned one at the same time.
The guy that did the work gave me the old one. It was in pieces.

and i think i already told you, the auto tensioner for the timing belt is crap on the 3.0L engine. If you start the car and hear a tapping noise for a second or two, that means its failing.
mitsubishi has a revised one.
the part number for that is
1145a062

You COULD but I dont know that you NEED to necessarily, although been that I'm ocd about stuff, I would probably have one on hand ready to go and then install it on a nice summer day when I am bored.
