Try letting up on the gas around the point where you think it would normally shift to 4th. If you get 4th then, but not as the fluid temp rises, then you know it's a pressure issue. You'll likely need to top up before starting it, especially if you've lost a significant amount of fluid during your testing. Fluid pressure is higher, when the fluid is cold. With the vehicle 'overnight cold' (8hr or more), check to see if you get 4th the first time you go through the gears after starting it up. The fact that this happened right after you swapped the servo points to that as the cause, IMO. If you've got twice that or more, then fluid can get past there (and you'll have lower fluid pressure, etc.) Usually, the excess play comes via wear - but since this is a new servo you put in, that shouldn't be an issue.

Also, check the free play with the servo - it should not have more than about 1/8' travel. Make sure the O-rings are seated correctly. However, it depends on sufficient fluid pressure to work correctly. I think if you're able to get that leak stopped (& top off fluid as needed), you'll get 4th again.Д«esides the 1-2 shift, the servo also has a function in the 3-4, as well. You can move / spin the clip inside the housing to get the clip surface exposed, if needed (after you have it reseated). There are slots at '3' and '6' o'clock of the housing - if you make sure a portion of the clip is visible through at least one of them, it'll be easier to remove the clip, if you ever have to work with the servo again. Might be tricky to do all of this with (only) two hands, under the vehicle. Once the entire clip is seated, release the inward pressure on the servo, and you should be set. Take care, as you don't want to break the outer portion of the housing that retains the clip - break enough of it off, and the clip won't hold the servo in. You may need to use a flat screwdriver to move / slide around the circumference of the housing, while guiding the clip into the slot with the tip of the screwdriver. Once the servo is in, you'll need to pry inward on the center cover a bit, to allow room for the retaining clip to be inserted - put the clip back in, and make sure it seats all the way around. When you removed the old one, did you wind up having to dig out the outer o-ring in order to be able to remove the servo? Same thing - but in reverse - it's a tight fit, especially w/ a new o-ring. That will help the servo & cover move forward into the case so that you can push it and the cover inward. Use TransJel or Vaseline to lube the outer edges of the servo o-rings, and the corresponding areas in the housing. Use a solvent if needed (brake parts cleaner spray works well) allow a few minutes to evaporate before inserting the new servo. Make sure the case area is clean - you want no residuals left from the old servo in the housing. I don't know what if anything you need to remove, but the more room you have the easier it will go for you. I believe I just reused the old push rod as I thought it was close enough. Be damned if you will be able to actually measure it and grind it down to fit. Telling you to ensure it has a certain clearance. The 'vette servo I last did had instructions about the piston rod length. Once you have the cover off very carefully lift the parts out making a mental note of how the springs are positioned. The spring behind it will push it out if the bore is free of corrosion. I don't know of any other way to pull that cover out of there. Tap the cover several times and it may work its way out. The corrosion above the C-clip groove must be removed before that cover will come out. Once the C-clip is out the cover will not pop out because of the corrosion. You will have to tap that cover down to release some of the tension on the C-clip so you can dig it out. You will want to smack that cover a few times to loosen it after you have let it soak. Their is pressure behind the cover, that and likely some corrosion.

Soak the C-clip groove with penetrating fluid because that C-clip will be stuck in there. Wash and blow away any dirt so when you have it open you don't get crap inside the trans.

What I can tell you is that once you do get to it, make sure everything around there is clean. I could take a look in the morning and see what I think would need to be moved. Well I can't tell you what needs to be removed as I haven't looked under mine for for a long time.
