New here,recent purchase 2002 3500 Chevy Express with shift problems/noise. 5.7l gas, hoping a Trans from same 2000 will interchange?

Possible 2000 donor is a slightly shorter delivery rig with a much larger diameter DL, mine has a 2 piece (15 passenger van).Welcome to the forum @Reacher120 iirc the 2000 and 02 should be the same. only thing you'll have to watch for is the tail shaft housing length. make sure that is the same so you don't need to swap out driveshafts. also be careful that one isn't a 4l85e or 90e trans. the 4l85's were more common in the newer rigs and both physically look the same. run the vin number with a GM dealer parts house to verify the RPO codes for the trans.
Torch, welder, drill, anything can fit.Anybody know if 2018 15 pass seats will fit a 2002 15 pass?
Both Chevy 3500 Express
My friend over in Elko has a 2012 or so Dodge, cummins and auto trans.Thanks for the welcome. Looks like this forum is geared toward Diesel owners, many seem to have the 4L80e Transmissions.
Please forgive this long post.
My transmission knowledge is limited, replacing filters and fluids, and pull and replace. Looking at a vehicle that had fluids and filter changed, was shifting fine, has now sat for 3 years. Starting up after almost 3 years, shifts are soft, feels like slippage into top 2 gear ranges; worst of all, making a "noise" like something rubbing on the drive line under acceleration. Gets up to Highway speed, no noises at cruising, good solid shifts manually in low/2, 3 seems slow.
Can just sitting gum up the works to cause these problems?
Gummed up Torque Converter?
Curious side symptoms:
Gear Indicator on dash is not working/illuminated
Previously working ( according to previous owner) Alternator not charging,was working prior to sitting.
My suspicion is that a jumper was hooked up backwards after sitting to start, and blew diodes in the alternator.
Is it possible (if that happened) it could have damaged some shift solenoid or something else in the trans?
I have a known good 4L80e trans available to swap from a 2000 Express 3500, but "someone" said a 2002 year Express 3500
is somehow all by itself. ??
If tail shafts are different, how big a job to swap?
Have my serial numbers of the 2002, going this morning to get numbers from 2000.
Who other than Forum members can verify this interchange?
Every Rebuilder I've contacted just wants to sell me a rebuilt unit (Spendy, can't blame them).
I've rebuilt many engines since 1970, never messed with AT's.
Now on SS, tying to save a buck. Hoping for a "Hail Mary" with either a flush/fluid/filter change, or used swap if it will fit.
Any insights would be appreciated!
Thanks,
Paul
And that was how Steve over in Elko was able to find His faulty connections.Great advice @MrMarty51 bad grounds and faulty connections can cause a multitude of oddities even in older rigs. Just a suggestion @Reacher120 while checking all the electrical system, get you a good multi-meter and a GM service manual with diagrams for your rig. Measuring in milli-volt and impedance between connections is a good way to locate faulty grounds and connections.
Do you have the part number to search with?Thanks for the reply.
The pans are identical.
I picked up a dipstick from a 2000 with a 6.0l and the same trans. it is slightly shorter but still feels like it is bottoming out.
The only way I'm going to be certain is order a new one from the dealer for $56 using the last 8 numbers of the VIN, unless I can find someone with the same year (and 5.7l) in an Express or Savannah that can measure for me!
I hate driving it with a possible incorrect fluid level.
2 weeks out from the dealer!
On a separate note, I am not finding much info on Front seat interchanges or compatible interior swaps.
The pedestals are surely taller, but there must be others seats that will bolt on!
