if your wonderingif the trans has proper pressure, hook up a 0-300 psi gauge to the main line port on the trans (driver side by the linkage) and see what the actual pressure is on the trans. the t-case will have nothing to do with a low pressure problem if it has low pressure.

I pulled the inspection cover off Poncho, still there
Thank you for the info and link Jon, so sad... When I first came on here I read so many Docvette posts and learned so many little things daily from him. Long live the Doc
tnsmith - DAMN YOU. That makes so much sense... I just don't want to hear it, lol. Any way you can think of to check it somehow without pulling it? If not, guess I'll be rebuilding my newly acquired 205 soon. That 203 has a weird shifter box mounted on top that gave me so much trouble whenever it got mud in it... No thank you.
And lastly, would that damage my transmission to drive it? Since it is the t-case not allowing total engagement rather than low pressure in the trans, think I'm ok? I don't plan on driving it much until it's fixed, but I DO need to keep moving it around, I usually take it to the store for milk and such here and there (strict city officials, whenever I park it a couple weeks they try to tow me )

the problem is the shift fork/s in the transfer case. they get worn and when they do, range engagement will lock but, the fork still moves from the wear and will make the noise as your describing.
i know it seems like a lot of work, ut id suggest that you put the 203 back inand see if the noise is still there.

Here's a link to a thread about him.

New T-350 rebuild makes grinding/scraping noise
Recently rebuilt by a local shop with a transtec rebuild kit, transgo shift kit, borg warner clutches and band, and a new converter (low stall/gas mileage tow converter). I flushed the cooler, and drove myself crazy making sure my converter was seated properly to the pump shaft.
Also, an NP205 was swapped in from the original 203 (went smoothly there).
Only happens when in gear and under load. If the t-case is in neutral, there is no noise, even when in foward or reverse gears. In Park or Neutral on the transmission (while in 2wd or 4wd) there is no noise. As soon as I put it under load (t-case engaged in any configuration, transmission in any gear) I get the noise. It sounds scarily like a bad converter install to me, BUT I know that not to be the case.
I quadruple checked on install, (double clunk to seat it, good spacing to the flexplate, freespinning TC both ways after bell was bolted up) and then pulled the flexplate bolts and shimmed it between plate and converter with 1/8" washers thinking maybe it was pulling on the flexplate too hard and causing runout. No luck. Converter still spun great with little to no effort when I took the bolts out to do this.
Feels a little soft for a shift kit and fresh rebuild also. Drove it about 2 1/2 miles trying to figure if it was just me or not, and decided to park it and not drive it anymore until I figure something out.
Been a long time, wheres the Doc at?
