AOD 1 to 3 shift?

[KamiKaziDK]

OD has been out for a few months and last week reverse went out so I picked up a used tranny off CL and swapped it in over the last couple days. Got all the fluid in and now when I'm driving it goes straight from 1st gear to 3rd and has a goofy little shimmy. Could this be because I have the TV cable set wrong or is it more likely that 2nd gear is just gone? I'm used to the electric tranny on my 95, so I'm pretty much No T5 comments, I'm broke right now, but it's planned for the future

Anyone?

Kick down or vacuum modulator

no vacuum modulator on an AOD, or kickdown for that matter.

I would start with making sure the TV cable is adjusted properly. What year is the CL AOD you got from, if you know?

The 89(I believe) and earlier AODs had an accumulator piston set up that could cause some issues. I am not sure if what you are describing is one of them.

I am assuming that the bad AOD was in your 90. If you need to you can swap the VB off the bad AOD into the one from CL and see if that helps take care of the problem. They changed the VB and moved the accumulator from a piston mounted in the trans body to one mounted in the VB. You can put a later VB on an older transmission but not the other way around. I have a 93 VB on my 88 AOD.

The only problem there is did the VB cause the problems in the original AOD. If so you might need to get some of the rebuild components for your VB from Baumann Electronic Controls Home Page

You might also want to post this question up on Click Click Racing as well. Lots of good tech and smart folks over there.

FYI There was a posting on one of the forums about that is what a B&M shift kit will do at low speed,it will shift from 1-2-3 while you are like still in the parking lots doing 25 mph.

I'll double check on what year both trannies are....just in case the one in it wasn't the original also. You can tell by checking the speedo gear inside the tail shaft, right? Also, I was just thinking.....could I do the 1-D-1 trick to force it into 2nd gear, or would that be bad?

1-d-1 is hard on the OD band. The main reason I ended up with an 88 trans in my 93.

 

[KamiKaziDK]

yeah, but even if the cable is set wrong, it would stay in 2nd if it's not bad, right? I haven't driven it at all yet cause I don't wanna make anything worse if it is the tv cable...and I really haven't had time.

When I did my real main seal and put the tranny back in the tv cable somehow got set wrong and it would not even shift. I noticed it when I took it around the block to test and it would not shift when I got up to 35.

How was it set wrong? I've got it routed up over the bellhousing and even used the bracket on the top pass. side bolt and got a brand new brass bushing kit from LMR. made sure on the tranny it was being pushed all the way to the tailshaft and then adjusted it up on the TB. I always get these retarded problems nobody is too sure about
