The transmission on my 1997 C1500 Suburban is done; I was pulling on to route 22 with moderate acceleration when I felt a big "thud" and an engine rev. The "Old Girl" kept going (she's so darn tough) but shifting is tentative and she has no reverse. I've had her since she was new and now have 275k miles on the original drivetrain with a new intake manifold gasket (5.7), fuel pump, 5 starters, and rear axle seals. Any suggestions on the replacement trans or what else I should have done during the process? I have been reading about Jasper reman units and wondered if anyone had any experience to share. I am not opposed to new or even an upgrade. I plan to keep this truck as long as I can and would love to see 500K come up on the odo some day. BTW this is not a job I plan to tackle myself as I don't currently have a good work space or the time (unfortunately) and I am open to suggestions and recommendations. Thanks in advance for feedback.
