Hi. I have a '93 245 auto I'm using as a winter car and have a problem with the transmission. The car shifts hard from 1rst to 2nd and then will stay in 2nd unless I let up on the gas. When I let up on the gas, it shifts from 2nd to 3rd, but won't go into OD.

When I got the car for parts, the fluid was low in the tranny and the electronic OD was shot. Since I was using it for parts, I didn't really care. After harvesting the parts I needed, the old car was still in pretty good shape, so I decided to ressurect it as a daily.

I added fluid to the tranny and put in an IPD overdrive bypass (have bypass on my '89 and love it!). I was hoping new fluid and bypass would solve the tranny issues, but not so much.

Before I drag it to a transmission shop, does anyone have an suggests about where to look/general help, etc. I'd hate to drag it to a shop and pay $$ to find out it was something stupid I missed.

Thanks!!

 

I'd verify the transmission throttle cable (often called kickdown cable) is retracting properly when you let up on the gas.

 

verify od relay working - jumper pin 15 & 87 at od connector with paper clip.

 

silvermine he already installed the IPD overdrive bypass plate, kinda late to be messing with the relay.

 

oh yes now see that line. there was a subscriber that installed the by-pass
and the OD still didn't work and then it did .... remember that?

that usually suggests some grit is plugging the hydraulic control labyrinth passages inside the transmission.

 

right u are. my own experience was that i got a brand new solenoid and it still did not work. took it off and blew out the passages for a couple of seconds with the solenoid off , replaced and voila it worked ....and has worked since other than a faulty od relay which was easily diagnosed/replaced.
