Im really beginning to dispise this stupid blazer. Yeah it was free, but its a damn money pit! Just when I thought everything was working great, all of a sudden it wont shift into reverse.

I drove the blazer to work this morning without a problem. After work, I go to reverse out of the parking spot and the tranny wont shift. I can move the column shifter to the reverse "gear"..... and thats it. Nuetral works, drive works, 4x4 works. WTF??? I even crawled under the truck to manually shift the tranny where the column shifter attatches to the link system on the tranny and moved that and still nothing.

I highly doubt this is directly related to my 2" body lift I just installed, but I could be wrong. Is anyone familiar with how the reverse works? Are there any electronic components or is it all in the tranny? Where should I start???

If it helps at all, since I did the body lift, it would take a few seconds for the reverse to actually engage after shifting. I would say a solid 3 full seconds.


PLEASE HELP!!!

 

Vehicle info?

 

sorry. I figured you guys would have memorized it by now lol.

1986 s10 blazer
2.8L
2" body lift
I believe its the original tranny. definitely not original motor.

 

Do all of the forward gears work?

If so, this could be a failure in the low-reverse roller clutch in the back of the trans. This clutch is supposed to free wheel when in a forward gear and lock up when in reverse. The thing that sucks is that you have to tear down the entire transmission to check it.

And sorry. With the number of people I respond to every day, it becomes a blur as far as remembering what everyone has.

 

understandable about the blurrs. I used to be a mod on a forum and I never payed attention to who was posting what unless they were a problem.

Is there any other possible explination for the loss of reverse? I drather not tear it down if I dont have to... especialyl since I have no idea what Id be looking for lol.

also, is it at all possible this is because of the body lift?

 

I doubt that the lift did anything unless it tweaked the linkage. Have you tried to adjust the shifter?

I read just about every post on this forum, but it typically is to make sure the content is appropriate for the given thread. I do not necessarily read what each and every person is driving unless they are the one having the problem.

 

I had to adjust the linkage/shifter after the body lift. The book said to find neutral with the linkage and then neutral with the shifter and tighten everything back up. It worked for a few days and today it just stopped working. When shifting into reverse, its acting as a second neutral. You can rev the engine, but nothing happens.

Could it be something as stupid as topping off my fluids? Im 95% sure the tranny fluid level is fine, but could that actually be a possible scenario?

 

It would not hurt to check the fluid level, but that typically causes problems in all gears, not just reverse.

Here is the symptom related problem areas for No-Reverse:

 

csnt see the pic at work but I will check it out when I get home. Thanks in advance!

Are there any electrical connections on the 700R4 tranny that might have been affected by my body lift?

 

None that affect shifting. It is all mechanical.
