Me and a friend has been installing a Transgo Shiftkit in my Camaros TH700R4, now for a couple of days, and we have doublechecked everything they told us to do, and in what order.

Right now, they only gears that work is 1:st gear and reverse, what might be my problem?

Where should I start my troubleshooting as to why it never upshifts from 1:st?

Also one thing that I noticed was that one of my checkballs were larger than the other ones used, but they never mentionen anywhere in the instrusctions where the larger ball should go, so I just used it like it'd been one of the regular *****.

anyone who has performed this shiftkit intsall successfully that'd like to help me out here?

There is one siple thing left, the shifter linkage, didn't have time to try that today. Will try tomorrow!

Hope I get this together soon, or I am in deep s**t because I have nowhere to keep the car for longer troubleshooting

 

I have never seen this before, but I'll try and help.

First off, that large checkball should get thrown away. If it wasn't in the picture, it shouldn't have been used. I guess thats TransGo's fault for not explaining it, because it really doesn't say anywhere, but it should not be there.

If you don't mind, walk me through what you did step by step and hopefully we can see where you went wrong. You may have skipped a step or did a step you were not supposed to do.

 

I didn't put more checkballs than the instructions told me to, I placed the larger checkball in the upper rightmost hole on the separator plate next to where the accumulator housing is located.

Do you have any idea why GM used one ball larger than the others originally?

A total of four checkballs on the separator plate, two in the valve body.

I am probably going out to the car later today to do some more troubleshooting, I'll get back to you when I have verified everything once more.

Lucky for me I put a drain plug in the oilpan so I won't have to get another tranny fluid shower

 

Okay, I have re-checked everything again.

The checkballs are where they are supposed to be, but I did find something that might be the cause of the problem.

Two checkballs in the valvebody, one in the aux valve body, four on the plate, and then the encapsulated reverse checkball in the upper part of the valvebody.

I might have used to few washers for the 2:nd and 4:th servo piston adjustment. I was careful not to use too many because they warned that too tight might burn the cluthes for that band.

In the installation guide, they say the band should be able to move on the drum about 1/16" to 3/16".

Could a too sloppy 2:nd/4:th band cause the transmission to not shift into 2:nd and higher at all or should it shift but slip very badly?

(Trying to eliminate possible causes to my problem one by one!).

The car does not seem to slip in 1:st and reverse, and the fluid level is just at the full mark when hot.

I am going to bring my digital camera next time I go out and work on the car, maybe some pictures could help see what I did wrong.

 

I think that my last post in this thread covers most of the questions I have about what might be the problem.

What are the most common misstakes that can cause the tranny to not upshift from 1:st?

 

Generally...after an install you have to give the tranny time to fill all the reseviors with fluid since they were basically drained. AFter my install we left it in teh air, and just let it shift by itself carefully to make sure they fluid was able to make its way into all the spots it needs to be. Mine was the same way (didn't want to shift to second, after a swap, but only because we had to drain it to replace the shifter detent bolt...starting to shift fine now...but still has a few minor glitches...

You might be able to give it time over a weeks or so before you start to question your ability to read directions. In worst case scenario...call TransGo and ask.

 

i had this problem with a metric 200 i had in an El Camino... come to find out the vacuum hose from the engin had rotted and fallen off and the tranny wasnt getting any vacuum.. might check that. its an easy fix.

 

Metric 200's do not have a vacuum modulator, the TH350's have one though.
