The '88 and '90 transmissions are pretty much interchangable. Assuming that it's a 5-speed, the '88 has the smaller pinion bearing and it sounds like the number of miles on it are unknown, so it's kind of a crapshoot. As long as you don't hear pinion bearing whine in 4th and 5th gear at 50 MPH and over, that won't be an immediate problem.
If it's an automatic transmission, they're the same between the 2 years. Same caveat about the unknown mileage.
The statement about the loose taillight bulb causing the CE light to go on in a C900 is a load of the old crapola. A bad O2 sensor can cause the CE light to stay on, among other things. To get a lead on what's actually happening in there, one needs to retrieve the codes from the ECU. Here's a link to the Townsend Imports page on the codes:
My initial guess is that the O2 sensor is bad, but there are other things that will cuse the light to stay on.
